There's essentially nothing that can be done. He's got a bunch of friends, anything you throw at him is put down as family values/overreaction. He's a troll, btw. It's been confirmed multiple times that he makes obnoxiously creepy posts to piss people off, and Badspot doesn't give a stuff. While I agree with the Drama I don't support the act of making a Drama in his name. It gets nothing done and he feeds off the attention. It's better to just let the bottom feeder pick up our scraps and just let him do his thing until he's bored.
Tempted to contact his parents/work through some information I picked up on him, not sure if they'd be too impressed with their employee/child/student being a potential child rapist.
