In a twist of irony, news of a bug that allowed Twitter users to cause other users to unknowingly follow them was quickly spread across the internet via social sites and popular blogs. The NYTimes Bits blog explains the discovery "The bug was first revealed by a Turkish man who wanted to tell his friends on Twitter about a band called “Accept” that he enjoyed listening too. When the man typed “Accept pwns” into the update box on Twitter he noticed that a user by the name of @pwns was now following him on the site."
Huh, sounds more like an Easter egg or developer backdoor than a bug...
