He's one of the leading shitposters in Niji, but at least in the past (not sure about now), he wasn't afraid to get toxic as fuck too.
Not remembering this 100% right, so take it with a pinch of salt, but in Niji's ARK universe (which in itself is worth watching, whole fuckton of interesting alliances and wars), Gwelu continuously built massive towers that intentionally lagged the server out. Someone (might've been Ex Albio, but I can't remember) would destroy them, but he'd always build more, ex. if his 16 lag towers went down, he'd put 64 back up. At some point their alliances went to war, and Gwelu broke the rules by destroying items/bases, which is pretty much what got him flamed into oblivion.
