I'm unaware of such, and would not participate in such. Your paranoia is drawing in innocent victims, apparently. I'm sorry you're going through that, but that doesn't justify you leaping to baseless accusations just because you remember my username.
I'll grant we've had disagreements before due to similar reactions on your part, but I always try to be respectful of others when they've done nothing wrong, and I try to treat each interaction as a new opportunity to communicate & understand one another. From previous interactions, I'd expect that to be an attitude you'd appreciate.
