These people are identical to the Wall street protestors, they hate the trolls but they don't give any successful ideas to prevent this!
There is a myriad of solutions to this problem. Stop being noobs so trolls aren't needed. Ignore it do you don't have to complain about it. Target the problem fail-trolls such as PWND and Garret.
