Honestly, I don't actively see how he's a troll currently. any posts of his i do see seem to be just fine. It could be he's actually trying to be better, but ya'll are given him a hard time simply because of what he's done in the past. I understand that he's been a troll, but sometimes people realize these things and actually stop.
Idk if he's done anything real recently, but from what i've actually seen, he's just trying to be cool and discuss things in topics, and he's almost instantly attacked every time. Do tell me if he's done anything recently though, I'll defend anyone until given evidence of their forgetery.
