Ahh, Chaos Chaos Chaos... you have much to learn about moderation. Though I\'m still learning much myself, let me tell you some hard-learnt lessons of my time here as a Mod.
1. Trolls want attention. Giving them any attention, let alone an ENTIRE thread, is very bad. You do not want people to discuss trolls, you want them to forget trolls. Making threads to \'warn\' people about trolls is counter-productive. It is better to make it seem like we never had the problem in the first place.
2. PMing a higher level mod is the best way to get their attention. Doing this, you can point out any offenders and the mess will be silently cleaned up without so much as a trace. That way, the troll never existed, nobody will ever remember his name, and thusly he does not get the attention he seeks.
3. Never start a thread where you do not wish people to discuss if you cannot close it.

With that said... *throws a padlock and goes to delete some posts elsewhere*
