my facebook account was blocked for no reason?

[Vegeta77]

well i just joined facebook about a month ago cause i just wanted to get in touch with some of my friends, since nobody i know uses google+. i used my real name and everything. all the info on my account was TRUE! i only have about 15 friends, and most of them i dont even chat with. i havent uploaded ANY pics that would be offensive. i dont post ANYTHING at all basically. and every time i try to log in, it says it dosnt think im a real person. ive went through the security check multiple times. today i went through security check again and it said i was spamming people and they have temporarily disabled my account. it would be helpful if facebook could tell me whats wrong BEFORE they block my account. does anybody know why my account got blocked? and how to stop this in the future?
