Why the fuck are you posting full names and facebook urls?
Posting the pictures is morally questionable.
Identifying the girls and telling randomers on the internet effectively where to find them is straight up criminal, and you should be going to fucking jail for that.
You're ruining loads of peoples careers and lives, the pictures show up for searches for their names for fucks sake.
If it were my daughter or something up on that site, you wouldn't be making this thread, but 6 feet in the ground. Irrespective of how stupid it is of her to send the pics to some guy in the first place.
If you didn't mention names and facebook urls, and watermark the photos, most people would have no idea you were the original publisher in the first place - which at least would give you a vague legal leg to stand on.
Any good lawyer acting on behalf of one of these girls could sue the shit out of you.
If you're going to keep running the site, at least take all the names and FB urls off.
Fuck do I hope someone catches up with you and teaches you a lesson though.
