Last week's announcement according to which Burger King was teaming up with social networking powerhouse Facebook for a special promotion violates the site’s privacy policy. The promotion gave out a voucher for a free Whopper sandwich if users removed friends from their Facebook network.

The burger empire has created a Facebook application, "Whopper Sacrifice", which gives users a free hamburger coupon if they delete 10 people from their friends list.

Therefore more than 233,906 friends were removed last week by 82,771 people who decided to take part in this promotion. This application facilitated activity that ran counter to user privacy by notifying people when a user removes a friend. In other words news of friend sacrifices were to appear in the activity feed, saying they were sacrificed for a free Whopper. How humiliating is that!

"We encourage creativity from developers and companies using Facebook Platform, but we also must ensure that applications follow users' expectations of privacy," said Facebook in a statement released late Wednesday. "After extensive discussions with the developer, we have not disabled the application but have placed some restrictions on the application to assure that users' expectations of privacy are maintained."

Crispin Porter + Bogusky and Refresh Partners, the agencies that developed the Whopper Sacrifice application, could not be reached for comment Wednesday.
