mykos writes "The Facebook groups feature is causing bit of a stir with its users. TechCrunch editor Michael Arrington was allegedly added to a group about NAMBLA, and in turn, he added Facebook CEO Mark Zuckerberg. It's all in good (albeit tasteless) fun, except when a harmless joke goes awry and you find yourself being detained by customs when a friend decided to drag you into a mock terrorist group. Facebook representatives are aware of the matter, but are dismissive of it. A Facebook spokeswoman said, 'If you have a friend that is adding you to Groups you do not want to belong to, or they are behaving in a way that bothers you, you can tell them to stop doing it, block them or remove them as a friend — and they will no longer EVER have the ability to add you to any Group.' In somewhat related news, guillotines ensure you won't have dandruff on your shoulders anymore."
