How to unban a Facebook account?

[Brandy]

Please help me get my Facebook back, I have tried contacting Facebook but they will not revive it.
The reason I got banned from Facebook is I was posting some pictures of me in my boyfriend on vacation and one of them had a tiny little fraction of my nipple visible. (So embarrassing) and every time I log in it said your account has been blocked for exploit pictures and it shows the picture
