Internet censorship
Legal control of the internet / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Internet censorship?
Summarize this article for a 10 year old
Internet censorship is the legal control or suppression of what can be accessed, published, or viewed on the Internet. Censorship is most often applied to specific internet domains (such as, Wikipedia.org) but exceptionally may extend to all Internet resources located outside the jurisdiction of the censoring state. Internet censorship may also put restrictions on what information can be made internet accessible.[1] Organizations providing internet access – such as schools and libraries – may choose to preclude access to material that they consider undesirable, offensive, age-inappropriate or even illegal, and regard this as ethical behavior rather than censorship. Individuals and organizations may engage in self-censorship of material they publish, for moral, religious, or business reasons, to conform to societal norms, political views, due to intimidation, or out of fear of legal or other consequences.[2][3]
The extent of Internet censorship varies on a country-to-country basis. While some countries have moderate Internet censorship, other countries go as far as to limit the access of information such as news and suppress and silence discussion among citizens.[3] Internet censorship also occurs in response to or in anticipation of events such as elections, protests, and riots. An example is the increased censorship due to the events of the Arab Spring. Other types of censorship include the use of copyrights, defamation, harassment, and various obscene material claims as a way to deliberately suppress content.
Support for and opposition to Internet censorship also varies. In a 2012 Internet Society survey 71% of respondents agreed that "censorship should exist in some form on the Internet". In the same survey 83% agreed that "access to the Internet should be considered a basic human right" and 86% agreed that "freedom of expression should be guaranteed on the Internet". Perception of internet censorship in the US is largely based on the First Amendment and the right for expansive free speech and access to content without regard to the consequences.[4] According to GlobalWebIndex, over 400 million people use virtual private networks to circumvent censorship or for increased user privacy.[5]
Many of the challenges associated with Internet censorship are similar to those for offline censorship of more traditional media such as newspapers, magazines, books, music, radio, television, and film. One difference is that national borders are more permeable online: residents of a country that bans certain information can find it on websites hosted outside the country. Thus censors must work to prevent access to information even though they lack physical or legal control over the websites themselves. This in turn requires the use of technical censorship methods that are unique to the Internet, such as site blocking and content filtering.[6]
Views about the feasibility and effectiveness of Internet censorship have evolved in parallel with the development of the Internet and censorship technologies:
- A 1993 Time Magazine article quotes computer scientist John Gilmore, one of the founders of the Electronic Frontier Foundation, as saying "The Net interprets censorship as damage and routes around it."[7]
- In November 2007, "Father of the Internet" Vint Cerf stated that he sees government control of the Internet failing because the Web is almost entirely privately owned.[8]
- A report of research conducted in 2007 and published in 2009 by the Berkman Center for Internet & Society at Harvard University stated that: "We are confident that the [ censorship circumvention ] tool developers will for the most part keep ahead of the governments' blocking efforts", but also that "...we believe that less than two percent of all filtered Internet users use circumvention tools."[9]
- In contrast, a 2011 report by researchers at the Oxford Internet Institute published by UNESCO concludes "... the control of information on the Internet and Web is certainly feasible, and technological advances do not therefore guarantee greater freedom of speech."[6]
Blocking and filtering can be based on relatively static blacklists or be determined more dynamically based on a real-time examination of the information being exchanged. Blacklists may be produced manually or automatically and are often not available to non-customers of the blocking software. Blocking or filtering can be done at a centralized national level, at a decentralized sub-national level, or at an institutional level, for example in libraries, universities or Internet cafes.[3] Blocking and filtering may also vary within a country across different ISPs.[10] Countries may filter sensitive content on an ongoing basis and/or introduce temporary filtering during key time periods such as elections. In some cases the censoring authorities may surreptitiously block content to mislead the public into believing that censorship has not been applied. This is achieved by returning a fake "Not Found" error message when an attempt is made to access a blocked website.[11]
Unless the censor has total control over all Internet-connected computers, such as in North Korea (who employs an intranet that only privileged citizens can access), or Cuba, total censorship of information is very difficult or impossible to achieve due to the underlying distributed technology of the Internet. Pseudonymity and data havens (such as Freenet) protect free speech using technologies that guarantee material cannot be removed and prevents the identification of authors. Technologically savvy users can often find ways to access blocked content. Nevertheless, blocking remains an effective means of limiting access to sensitive information for most users when censors, such as those in China, are able to devote significant resources to building and maintaining a comprehensive censorship system.[6]
The term "splinternet" is sometimes used to describe the effects of national firewalls. The verb "rivercrab" colloquially refers to censorship of the Internet, particularly in Asia.[12]
Technical censorship
Various parties are using different technical methods of preventing public access to undesirable resources, with varying levels of effectiveness, costs and side effects.
Blacklist
Entities mandating and implementing the censorship usually identify them by one of the following items: keywords, domain names and IP addresses. Lists are populated from different sources, ranging from private supplier through courts to specialized government agencies (Ministry of Industry and Information Technology of China, Islamic Guidance in Iran).[13]
As per Hoffmann, different methods are used to block certain websites or pages including DNS poisoning, blocking access to IPs, analyzing and filtering URLs, inspecting filter packets and resetting connections.[14]
Points of control
Enforcement of the censor-nominated technologies can be applied at various levels of countries and Internet infrastructure:[13]
- Internet backbone, including Internet exchange points (IXP) with international networks (Autonomous Systems), operators of submarine communications cables, satellite Internet access points, international optical fibre links etc. In addition to facing huge performance challenges due to large bandwidths involved, these do not give censors access to information exchanged within the country.
- Internet Service Providers, which involves installation of voluntary (as in UK) or mandatory (as in Russia) Internet surveillance and blocking equipment.
- Individual institutions, which in most cases implement some form of Internet access controls to enforce their own policies, but, especially in case of public or educational institutions, may be requested or coerced to do this on the request from the government.
- Personal devices, whose manufacturers or vendors may be required by law to install censorship software.
- Application service providers (e.g. social media companies), who may be legally required to remove particular content. Foreign providers with business presence in given country may be also coerced into restricting access to specific contents for visitors from the requesting country.
- Certificate authorities may be required to issue counterfeit X.509 certificates controlled by the government, allowing man-in-the-middle surveillance of TLS encrypted connections.
- Content Delivery Network providers who tend to aggregate large amounts of content (e.g. images) may be also attractive target for censorship authorities.
Approaches
Internet content is subject to technical censorship methods, including:[3][6]
- Internet Protocol (IP) address blocking: Access to a certain IP address is denied. If the target Web site is hosted in a shared hosting server, all websites on the same server will be blocked. This affects IP-based protocols such as HTTP, FTP and POP. A typical circumvention method is to find proxies that have access to the target websites, but proxies may be jammed or blocked, and some Web sites, such as Wikipedia (when editing), also block proxies. Some large websites such as Google have allocated additional IP addresses to circumvent the block, but later the block was extended to cover the new addresses[citation needed]. Due to challenges with geolocation, geo-blocking is normally implemented via IP address blocking.
- Domain name system (DNS) filtering and redirection: Blocked domain names are not resolved, or an incorrect IP address is returned via DNS hijacking or other means. This affects all IP-based protocols such as HTTP, FTP and POP. A typical circumvention method is to find an alternative DNS resolver that resolves domain names correctly, but domain name servers are subject to blockage as well, especially IP address blocking. Another workaround is to bypass DNS if the IP address is obtainable from other sources and is not itself blocked. Examples are modifying the Hosts file or typing the IP address instead of the domain name as part of a URL given to a Web browser.
- Uniform Resource Locator (URL) filtering: URL strings are scanned for target keywords regardless of the domain name specified in the URL. This affects the HTTP protocol. Typical circumvention methods are to use escaped characters in the URL, or to use encrypted protocols such as VPN and TLS/SSL.[15]
- Packet filtering: Terminate TCP packet transmissions when a certain number of controversial keywords are detected. This affects all TCP-based protocols such as HTTP, FTP and POP, but Search engine results pages are more likely to be censored. Typical circumvention methods are to use encrypted connections – such as VPN and TLS/SSL – to escape the HTML content, or by reducing the TCP/IP stack's MTU/MSS to reduce the amount of text contained in a given packet.
- Connection reset: If a previous TCP connection is blocked by the filter, future connection attempts from both sides can also be blocked for some variable amount of time. Depending on the location of the block, other users or websites may also be blocked, if the communication is routed through the blocking location. A circumvention method is to ignore the reset packet sent by the firewall.[16]
- Network disconnection: A technically simpler method of Internet censorship is to completely cut off all routers, either by software or by hardware (turning off machines, pulling out cables). A circumvention method could be to use a satellite ISP to access Internet.[17]
- Portal censorship and search result removal: Major portals, including search engines, may exclude web sites that they would ordinarily include. This renders a site invisible to people who do not know where to find it. When a major portal does this, it has a similar effect to censorship. Sometimes this exclusion is done to satisfy a legal or other requirement, other times it is purely at the discretion of the portal. For example, Google.de and Google.fr remove Neo-Nazi and other listings in compliance with German and French law.[18]
- Computer network attacks: Denial-of-service attacks and attacks that deface opposition websites can produce the same result as other blocking techniques, preventing or limiting access to certain websites or other online services, although only for a limited period of time. This technique might be used during the lead up to an election or some other sensitive period. It is more frequently used by non-state actors seeking to disrupt services.[19]

Over and under blocking
Technical censorship techniques are subject to both over- and under-blocking since it is often impossible to always block exactly the targeted content without blocking other permissible material or allowing some access to targeted material and so providing more or less protection than desired.[6] An example is blocking an IP-address of a server that hosts multiple websites, which prevents access to all of the websites rather than just those that contain content deemed offensive.[20]
Use of commercial filtering software
Writing in 2009 Ronald Deibert, professor of political science at the University of Toronto and co-founder and one of the principal investigators of the OpenNet Initiative, and, writing in 2011, Evgeny Morzov, a visiting scholar at Stanford University and an Op-Ed contributor to the New York Times, explain that companies in the United States, Finland, France, Germany, Britain, Canada, and South Africa are in part responsible for the increasing sophistication of online content filtering worldwide. While the off-the-shelf filtering software sold by Internet security companies are primarily marketed to businesses and individuals seeking to protect themselves and their employees and families, they are also used by governments to block what they consider sensitive content.[21][22]
Among the most popular filtering software programs is SmartFilter by Secure Computing in California, which was bought by McAfee in 2008. SmartFilter has been used by Tunisia, Saudi Arabia, Sudan, the UAE, Kuwait, Bahrain, Iran, and Oman, as well as the United States and the UK.[23] Myanmar and Yemen have used filtering software from Websense. The Canadian-made commercial filter Netsweeper[24] is used in Qatar, the UAE, and Yemen.[25] The Canadian organization CitizenLab has reported that Sandvine and Procera products are used in Turkey and Egypt.[26]
On 12 March 2013 in a Special report on Internet Surveillance, Reporters Without Borders named five "Corporate Enemies of the Internet": Amesys (France), Blue Coat Systems (U.S.), Gamma (UK and Germany), Hacking Team (Italy), and Trovicor (Germany). The companies sell products that are liable to be used by governments to violate human rights and freedom of information. RWB said that the list is not exhaustive and will be expanded in the coming months.[27]
In a U.S. lawsuit filed in May 2011, Cisco Systems is accused of helping the Chinese Government build a firewall, known widely as the Golden Shield, to censor the Internet and keep tabs on dissidents.[28] Cisco said it had made nothing special for China. Cisco is also accused of aiding the Chinese government in monitoring and apprehending members of the banned Falun Gong group.[29]
Many filtering programs allow blocking to be configured based on dozens of categories and sub-categories such as these from Websense: "abortion" (pro-life, pro-choice), "adult material" (adult content, lingerie and swimsuit, nudity, sex, sex education), "advocacy groups" (sites that promote change or reform in public policy, public opinion, social practice, economic activities, and relationships), "drugs" (abused drugs, marijuana, prescribed medications, supplements and unregulated compounds), "religion" (non-traditional religions occult and folklore, traditional religions), ....[25] The blocking categories used by the filtering programs may contain errors leading to the unintended blocking of websites.[21] The blocking of Dailymotion in early 2007 by Tunisian authorities was, according to the OpenNet Initiative, due to Secure Computing wrongly categorizing Dailymotion as pornography for its SmartFilter filtering software. It was initially thought that Tunisia had blocked Dailymotion due to satirical videos about human rights violations in Tunisia, but after Secure Computing corrected the mistake access to Dailymotion was gradually restored in Tunisia.[30]
Organizations such as the Global Network Initiative, the Electronic Frontier Foundation, Amnesty International, and the American Civil Liberties Union have successfully lobbied some vendors such as Websense to make changes to their software, to refrain from doing business with repressive governments, and to educate schools who have inadvertently reconfigured their filtering software too strictly.[31][32][33] Nevertheless, regulations and accountability related to the use of commercial filters and services are often non-existent, and there is relatively little oversight from civil society or other independent groups. Vendors often consider information about what sites and content is blocked valuable intellectual property that is not made available outside the company, sometimes not even to the organizations purchasing the filters. Thus by relying upon out-of-the-box filtering systems, the detailed task of deciding what is or is not acceptable speech may be outsourced to the commercial vendors.[25]
Non-technical censorship
Internet content is also subject to censorship methods similar to those used with more traditional media. For example:[6]
- Laws and regulations may prohibit various types of content and/or require that content be removed or blocked either proactively or in response to requests.
- Publishers, authors, and ISPs may receive formal and informal requests to remove, alter, slant, or block access to specific sites or content.
- Publishers and authors may accept bribes to include, withdraw, or slant the information they present.
- Publishers, authors, and ISPs may be subject to arrest, criminal prosecution, fines, and imprisonment.
- Publishers, authors, and ISPs may be subject to civil lawsuits.
- Equipment may be confiscated and/or destroyed.
- Publishers and ISPs may be closed or required licenses may be withheld or revoked.
- Publishers, authors, and ISPs may be subject to boycotts.
- Publishers, authors, and their families may be subject to threats, attacks, beatings, and even murder.[34]
- Publishers, authors, and their families may be threatened with or actually lose their jobs.
- Individuals may be paid to write articles and comments in support of particular positions or attacking opposition positions, usually without acknowledging the payments to readers and viewers.[35][36]
- Censors may create their own online publications and Web sites to guide online opinion.[35]
- Access to the Internet may be limited due to restrictive licensing policies or high costs.
- Access to the Internet may be limited due to a lack of the necessary infrastructure, deliberate or not.
- Access to search results may be restricted due to government involvement in the censorship of specific search terms, content may be excluded due to terms set with search engines. By allowing search engines to operate in new territory they must agree to abide to censorship standards set by the government in that country.[37]
Censorship of users by web service operators
Removal of user accounts based on controversial content
Deplatforming is a form of Internet censorship in which controversial speakers or speech are suspended, banned, or otherwise shut down by social media platforms and other service providers that generally provide a venue for free speech or expression.[38] Banking and financial service providers, among other companies, have also denied services to controversial activists or organizations, a practice known as "financial deplatforming".
Law professor Glenn Reynolds dubbed 2018 the "Year of Deplatforming", in an August 2018 article in The Wall Street Journal.[38] According to Reynolds, in 2018 "the internet giants decided to slam the gates on a number of people and ideas they don't like."[38] On 6 August 2018, for example, several major platforms, including YouTube and Facebook, executed a coordinated, permanent ban on all accounts and media associated with conservative talk show host Alex Jones and his media platform InfoWars, citing "hate speech" and "glorifying violence."[39]
Official statements regarding site and content removal
Most major web service operators reserve to themselves broad rights to remove or pre-screen content, and to suspend or terminate user accounts, sometimes without giving a specific list or only a vague general list of the reasons allowing the removal. The phrases "at our sole discretion", "without prior notice", and "for other reasons" are common in Terms of Service agreements.
- Facebook: Among other things, the Facebook Statement of Rights and Responsibilities says: "You will not post content that: is hateful, threatening, or pornographic; incites violence; or contains nudity or graphic or gratuitous violence", "You will not use Facebook to do anything unlawful, misleading, malicious, or discriminatory", "We can remove any content or information you post on Facebook if we believe that it violates this Statement", and "If you are located in a country embargoed by the United States, or are on the U.S. Treasury Department's list of Specially Designated Nationals you will not engage in commercial activities on Facebook (such as advertising or payments) or operate a Platform application or website".[40]
- Google: Google's general Terms of Service, which were updated on 1 March 2012, state: "We may suspend or stop providing our Services to you if you do not comply with our terms or policies or if we are investigating suspected misconduct", "We may review content to determine whether it is illegal or violates our policies, and we may remove or refuse to display content that we reasonably believe violates our policies or the law", and "We respond to notices of alleged copyright infringement and terminate accounts of repeat infringers according to the process set out in the U.S. Digital Millennium Copyright Act".[41]
- Google Search: Google's Webmaster Tools help includes the following statement: "Google may temporarily or permanently remove sites from its index and search results if it believes it is obligated to do so by law, if the sites do not meet Google's quality guidelines, or for other reasons, such as if the sites detract from users' ability to locate relevant information."[42]
- Twitter: The Twitter Terms of Service state: "We reserve the right at all times (but will not have an obligation) to remove or refuse to distribute any Content on the Services and to terminate users or reclaim usernames" and "We reserve the right to remove Content alleged to be copyright infringing without prior notice and at our sole discretion".[43]
- YouTube: The YouTube Terms of Service include the statements: "YouTube reserves the right to decide whether Content violates these Terms of Service for reasons other than copyright infringement, such as, but not limited to, pornography, obscenity, or excessive length. YouTube may at any time, without prior notice and in its sole discretion, remove such Content and/or terminate a user's account for submitting such material in violation of these Terms of Service", "YouTube will remove all Content if properly notified that such Content infringes on another's intellectual property rights", and "YouTube reserves the right to remove Content without prior notice".[44]
- Wikipedia: The site's content may be modified or deleted by any editor as part of the normal process of editing and updating articles. Wikipedia's deletion policy outlines the circumstances in which entire articles can be deleted. Any editor who believes a page doesn't belong in the encyclopedia can propose its deletion. Such a page can be deleted by any administrator if, after seven days, no one objects to the proposed deletion. Speedy deletion allows for outright deletion of articles that are so clearly in violation of rules of the website that they do not need to undergo a full deletion discussion. All deletion decisions may be reviewed, either informally or formally. An additional means of hiding specific content within Wikipedia articles is revision deletion, or RevDel, by which an administrator can perform sanitization/redaction of specific revisions of an article, thereby hiding certain information from the view of non-administrators.[45][46]: 216
- Yahoo!: Yahoo!'s Terms of Service (TOS) state: "You acknowledge that Yahoo! may or may not pre-screen Content, but that Yahoo! and its designees shall have the right (but not the obligation) in their sole discretion to pre-screen, refuse, or remove any Content that is available via the Yahoo! Services. Without limiting the foregoing, Yahoo! and its designees shall have the right to remove any Content that violates the TOS or is otherwise objectionable."[47]
Internet censorship circumvention is one of the processes used by technologically savvy Internet users to bypass the technical aspects of Internet filtering and gain access to the otherwise censored material. Circumvention is an inherent problem for those wishing to censor the Internet because filtering and blocking do not remove content from the Internet, but instead block access to it. Therefore, as long as there is at least one publicly accessible uncensored system, it will often be possible to gain access to the otherwise censored material. However circumvention may not be possible by non-tech-savvy users, so blocking and filtering remain effective means of censoring the Internet access of large numbers of users.[6]
Different techniques and resources are used to bypass Internet censorship, including proxy websites, virtual private networks, sneakernets, the dark web and circumvention software tools. Solutions have differing ease of use, speed, security, and risks. Most, however, rely on gaining access to an Internet connection that is not subject to filtering, often in a different jurisdiction not subject to the same censorship laws. According to GlobalWebIndex, over 400 million people use virtual private networks to circumvent censorship or for an increased level of privacy.[5] The majority of circumvention techniques are not suitable for day to day use.[48]
There are risks to using circumvention software or other methods to bypass Internet censorship. In some countries, individuals that gain access to otherwise restricted content may be violating the law and if caught can be expelled, fired, jailed, or subject to other punishments and loss of access.[3][49]
In June 2011 the New York Times reported that the U.S. is engaged in a "global effort to deploy 'shadow' Internet and mobile phone systems that dissidents can use to undermine repressive governments that seek to silence them by censoring or shutting down telecommunications networks."[50]
Another way to circumvent Internet censorship is to physically go to an area where the Internet is not censored. In 2017 a so-called "Internet refugee camp" was established by IT workers in the village of Bonako, just outside an area of Cameroon where the Internet is regularly blocked.[51][52]
Increased use of HTTPS
The use of HTTPS versus what originally was HTTP in web searches created greater accessibility to most sites originally blocked or heavily monitored. Many social media sites including, Facebook, Google, and Twitter have added an automatic redirection to HTTPS as of 2017.[53] With the added adoption of HTTPS use, "censors" are left with limited options of either completely blocking all content or none of it.[54]
The use of HTTPS does not inherently prevent the censorship of an entire domain, as the domain name is left unencrypted in the ClientHello of the TLS handshake. The Encrypted Client Hello TLS extension expands on HTTPS and encrypts the entire ClientHello but this depends on both client and server support.[55][56]
There are several motives or rationales for Internet filtering: politics and power, social norms and morals, and security concerns. Protecting existing economic interests is an additional emergent motive for Internet filtering. In addition, networking tools and applications that allow the sharing of information related to these motives are themselves subjected to filtering and blocking. And while there is considerable variation from country to country, the blocking of web sites in a local language is roughly twice that of web sites available only in English or other international languages.[11]
Politics and power
Censorship directed at political opposition to the ruling government is common in authoritarian and repressive regimes. Some countries block web sites related to religion and minority groups, often when these movements represent a threat to the ruling regimes.[11]
Examples include:
- Political blogs and websites[57]
- Lèse-majesté sites, sites with content that offends the dignity of or challenges the authority of a reigning sovereign or of a state
- Falun Gong and Tibetan exile group sites in China or Buddhist, Cao Dai faith, and indigenous hill tribes sites in Vietnam
- 50 Cent Party, or "50 Cent Army" that worked to sway negative public opinion on the Chinese Communist Party[58]
- Russian web brigades
- Sites aimed at religious conversion from Islam to Christianity[11]
- Sites criticizing the government or an authority in the country[59]
- Sites that comment on political parties that oppose the current government of a country[59]
- Sites that accuse authorities of corruption[59]
- Sites that comment on minorities or LGBTQ+ issues[59]
- Communist symbols and imagery in Poland, Lithuania, Ukraine, Georgia, Latvia, Moldova, Hungary, and Indonesia
- Nazi and similar websites, particularly in France and Germany[60]
Social norms
Social filtering is censorship of topics that are held to be antithetical to accepted societal norms.[11] In particular censorship of child pornography and content deemed inappropriate for children enjoys very widespread public support and such content is subject to censorship and other restrictions in most countries.
Examples include:
- Sites that include hate speech inciting racism, sexism, homophobia, or other forms of bigotry
- Sites seen as promoting illegal drug use (Erowid)[61]
- Sex and erotic, fetishism, prostitution, and pornographic sites
- Child pornography and pedophile related sites (see also CIRCAMP)
- Gambling sites
- Sites encouraging or inciting violence[59]
- Sites promoting criminal activity[59]
- Sites that contain blasphemous content, particularly when directed at a majority or state supported religion[59]
- Sites that contain defamatory, slanderous, or libelous content[59]
- Sites that include political satire[59]
- Sites that contain information on social issues or "online protests, petitions and campaigns"[59]
Security concerns
Many organizations implement filtering as part of a defense in depth strategy to protect their environments from malware,[62] and to protect their reputations in the event of their networks being used, for example, to carry out sexual harassment.
Internet filtering related to threats to national security that targets the Web sites of insurgents, extremists, and terrorists often enjoys wide public support.[11]
Examples include:
- Blocking of pro–North Korean sites by South Korea[63]
- Blocking sites of groups that foment domestic conflict in India[11]
- Blocking of sites of the Muslim Brotherhood in some countries in the Middle East
- Blocking sites such as 4chan thought to be related to the group Anonymous[64]
Protection of existing economic interests and copyright
The protection of existing economic interests is sometimes the motivation for blocking new Internet services such as low-cost telephone services that use Voice over Internet Protocol (VoIP). These services can reduce the customer base of telecommunications companies, many of which enjoy entrenched monopoly positions and some of which are government sponsored or controlled.[11]
Anti-copyright activists Christian Engström, Rick Falkvinge and Oscar Swartz have alleged that censorship of child pornography is being used as a pretext by copyright lobby organizations to get politicians to implement similar site blocking legislation against copyright-related piracy.[65]
Examples include:
- File sharing and peer-to-peer (P2P) related websites such as The Pirate Bay
- Skype
- Sites that sell or distribute music, but are not 'approved' by rights holders, such as allofmp3
Network tools
Blocking the intermediate tools and applications of the Internet that can be used to assist users in accessing and sharing sensitive material is common in many countries.[11]
Examples include:
- Media sharing websites (e.g. Flickr and YouTube)[66]
- Social networks (e.g. Facebook and Instagram)
- Translation sites and tools
- E-mail providers
- Web hosting sites
- Blog hosting sites such as Blogspot and Medium
- Microblogging sites such as Twitter and Weibo[67]
- Wikipedia
- Censorship circumvention sites
- Search engines such as Bing[68] and Google[69][70] – particularly in Mainland China and Cuba[71]
Information about individuals
The right to be forgotten is a concept that has been discussed and put into practice in the European Union. In May 2014, the European Court of Justice ruled against Google in Costeja, a case brought by a Spanish man who requested the removal of a link to a digitized 1998 article in La Vanguardia newspaper about an auction for his foreclosed home, for a debt that he had subsequently paid.[72] He initially attempted to have the article removed by complaining to Spain's data protection agency—Agencia Española de Protección de Datos—which rejected the claim on the grounds that it was lawful and accurate, but accepted a complaint against Google and asked Google to remove the results.[73] Google sued in Spain and the lawsuit was transferred to the European Court of Justice. The court ruled in Costeja that search engines are responsible for the content they point to and thus, Google was required to comply with EU data privacy laws.[74][75] It began compliance on 30 May 2014 during which it received 12,000 requests to have personal details removed from its search engine.[76]
Index on Censorship claimed that "Costeja ruling ... allows individuals to complain to search engines about information they do not like with no legal oversight. This is akin to marching into a library and forcing it to pulp books. Although the ruling is intended for private individuals it opens the door to anyone who wants to whitewash their personal history....The Court's decision is a retrograde move that misunderstands the role and responsibility of search engines and the wider internet. It should send chills down the spine of everyone in the European Union who believes in the crucial importance of free expression and freedom of information."[77]
Various contexts influence whether or not an internet user will be resilient to censorship attempts. Users are more resilient to censorship if they are aware that information is being manipulated. This awareness of censorship leads to users finding ways to circumvent it. Awareness of censorship also allows users to factor this manipulation into their belief systems. Knowledge of censorship also offers some citizens incentive to try to discover information that is being concealed. In contrast, those that lack awareness of censorship cannot easily compensate for information manipulation.[78]
Other important factors for censorship resiliency are the demand for the information being concealed, and the ability to pay the costs to circumvent censorship. Entertainment content is more resilient to online censorship than political content, and users with more education, technology access, and wider, more diverse social networks are more resilient to censorship attempts.[78]
