It was slayer, and he is gone.
His old name as those who read Schlottke's post after I teased what I had found out had likely surmised was Password who I banned 3 months ago after he decided he was going to start bringing people's kids into arguments he had on here.
Both slayer and Password had posts from the same California IP address, and the name slayer was registered about twenty minutes after I banned Password who had threatened that if I banned him he'd come right back. The IP match wasn't coincidental, as I had Schlottke check it and it was the same guy.
He may try and come back again, but I don't think it'll be successful this time. Dude was treading on thin ice anyway, telling people to kill themselves just isn't cool.
