The internet doesn't work that way. When the trolls come out, don't engage them. Trying to correct them like they are bratty children is exactly what they want and it completely throws the thread off the rails.
Just ignore their posts. If they post something stupid and contrary just let it slide and before you know it there is a new page and what One Ball Saul
said is forgotten.
Being overly nannyish with censoring and bannings just shuts down real conversation and creates the echo chamber that kills traffic on most message boards.
There was about three straight pages of people biting the hook on Peepers' troll yesterday. That feeds the troll and stopped the thread dead. Just ignore stupid comments from posters you know to be doing it simply to provoke.
