By using Facebook, you agree to grant Facebook an irrevocable, perpetual right to use any material you post there for any purpose they wish. This was all fine with me, since they also have a moderation clause: You can revoke the irrevocable right (makes sense eh?) by terminating your account. This provides you with a sort of backup escape route if hell breaks lose and Facebook starts using your content or your information in ways you don’t like.
I don’t think it’s likely that Facebook will abuse my info in any way, but I’m not willing to take the chance. And I get really mad when companies throw terms at me that are so wildly imbalanced. To illustrate, assume you were playing cards with someone. But that someone you’re playing with reserves the right to change the rules at will. You on the other hand can’t suggest rules, and you automatically agree to new rules by continuing to play. The rules start out saying that he scores a point whenever he gets a spades, clubs or hearts card. You only get half a point if you happen to get the queen of spades. After a while, you grow tired of this game (your odds of winning are pretty low, and the game is pretty boring). But your friend likes the game so much (because he’s winning big time), and he senses you’re about to leave. He thus invents a new rule that prohibits you from ever leaving, and you automatically agree by picking up the next card. What do you do?
