If you haven't already publicly forsaken all your Facebook friends in order to earn a Whopper, it's too late. Facebook has crippled the Burger King "Whopper Sacrifice" anti-friendship widget for being too mean.

Facebook cut off the feature that actually told the world that you had un-friended so and so in pursuit of a coupon for a mayonaisse-soaked slab of cow.

"After it learned of the restrictions, BK pulled the plug on Whopper Sacrifice. In just a week, the application boasted 82,000 users and more than 230,000 friends removed."

You're all very bad, fat people. [Adweek]
