Trolls, Griefers & Whatever Else that Lurks in L4D2 Land

[Doc]

I'm sure this topic has been discussed before but I have seen a major increase in the Griefers in game lately since it went on sale. I have the screen names of 2 that trolled me & my friend when I was playing the Parish on expert to help my buddy get the achievement for expert. I will post those names later of the 2 I mentioned in a effort that other players can avoid them.
