Facebook de-friends Burger King:
Facebook is no longer friends with Burger King, which it charges improperly used the site to pump up biz by offering users a free Whopper sandwich if they dumped 10 of their pals on the social-networking site.
Facebook disabled the fast-food chain's "Whopper Sacrifice" app this week, saying that it violated the site's privacy
policy by alerting users when they were de-friended. Under normal
circumstances, de-friending is a quiet, anonymous act; Facebook doesn’t
inform you if you've been dumped.
