I personally left (or was forced to) Facebook because I kept getting hacked by one of those organizations that hacked buttloads of accounts to then use them to like-selling. After so much trouble, trying to recover my account I just gave up and permanently deleted my account (after two weeks of disabling the account, it deletes perma). I had that account since 2007. Nine whole years...to be honest, i am glad I left. There's so much drama among the groups, fans, friends and people that it got ridiculous in my opinion.
