Whopper Sacrifice

Whopper Sacrifice was an advertising campaign by Burger King which was launched in January 2009.^[1][2] After unfriending 10 people on Facebook, people were eligible for a free Whopper by Burger King. Apparently, Burger King told them that they were worth “1/10th of a Whopper”. The app was disabled by Facebook.^[3] The campaign was developed by Crispin Porter + Bogusky.^[4][5]
