it's been relatively quiet of trolls lately actually. i remember forums being much worse some 6 months ago or so. moderators and thread locking already exists afaik though.
As Turtle said, I disagree that they have been quiet. Apparently you have missed all the blatant racial and other slurs on here in the last couple weeks as well.
As far as your 2nd point about mods. I'm not sure those functions exist (they may, but he has not been public about it). I am sure Fizzer (and probably Mercer) can lock threads, delete, etc. I highly doubt anyone else can. I do know these can be done:
1) promote threads
2) move threads
3) alt checking
Outside that, I have no idea if anyone not on the warlight staff can do anything else. And of those 3 abilities, I know of a few people that have some of those abilities but not all. But, I am guessing nobody beyong Fizzer/Mercer has the power to do any real moderating because they would do stuff (say edit a post) and right now the board is not set up to denote who changed something. He's too smart to give that control without transparency or he'd get accused of everything.
Apparently Krzychu has access to the seasonal ladder data too. I guess these boards seem to have puppets behind the scenes where we have no idea who can do what. it would be nice to have designated mods with tools so everyone knows why things are done.
