Remember this: Facebook can only use/misuse information YOU GIVE THEM. You don’t have to use your real name, email address or anything else. It’s up to you. You don’t have to post any pictures or have any friends (though that would be sad).
Due to my previous profession, I was as concerned as anyone with their old policies and the very real threat to me and my family if my information was not secure - And remember this, you can use any name or email address you want. So even if Facebook is working with NSA to steal your info, you'll be one step ahead in this game of Spy V Spy!
