Damn that's a lot of alts, I was going to suggest IP bans but people can still go via proxy but that would be pretty desperate of someone to go that far to make a few alts to troll/flame.
I also noticed some people while using their originals, create alts in a form to let loose on someone, I don't see the point in that tbh because it links back to you and gets your original banned and points us all to who it originally was, the alt doesn't hide you so why do it?.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
