Yeah facebook doesn't like nudity! I remember I posted a pic of me eating bacon out of my friends underwear (long story :D) and facebook wouldn't let me keep it coz they kept thinking it was porn. I eventually had to email someone and tell them to look at it properly.
Good luck anyway
Actually, I have a spare fb account, I had to open it coz I got banned from uploading videos (long story :D) so I'll add you on it
