I thought the thagomizer was your actual boyfriend. And nomaken had a thing for you online.
I don't often recall things well, like I used to.
He was, at one point, when I was still very young and stupid. When I wised up and broke up with him, he proceeded to make a fake account on there to monitor me post-breakup, as well as some really creepy-ass shit IRL, which had friends as well as myself worried about how much it might escalate. He, thank god, stopped (at least with me, anyway) before I actually reached the point of filing a restraining order. It did reach a point where I was starting to consider it.
Nomaken was never someone I was worried about. There have been a couple of other guys on here I'd never want to have know where I live, though. Peaguy was a good example (and also an example that blew up relatively publicly)- he asked several members (including me) for their home addresses, supposedly to send cards to. I didn't trust him, and thusly didn't get burned; to my knowledge, at least one other member had Peaguy pull some really bad shit on him.
There've been a few other folks on here over the years who've given off manic/obsessive/creepy vibes that have gotten my hackles up. Not super-often, but enough that I trust my instincts.
