There is a very easy solution, now that we have an option to ban members from certain threads.
Just ban Sheik from Vucinic's thread. He's doing nothing else but trolling. Ban the group in Matri's thread that does nothing else but make fun of Matri. Same with those in Quag's thread. If not all of them, since there are many bandwagoners, ban only the 3 most active from each group. Ban them all for 2-3 weeks. It will be a lesson for the others.
If they find a new thread to continue their little war, then give them a 3 week ban from the forum.
