yeah that numbers guy came and went after all the sonic vs wallyfagging. I heard he was here briefly during the zuko vs whatshisname fight as well but I didn't browse those threads at the time so I don't know.
The capeworld guy has been here for awhile though. As for when he started posting? I don't know, but according to >>118644235
it's been since the ben vs hal days.
All I know is that almost every "Death battle" thread has been revolving around this one tripfag. Which is weird because most other boards absolutely despise tripfags and usually ignores them. But this one even seems to have his own fans for some reason.
