Something can always be done if needed which is why I tend to game on private servers.
-_oDo you really think you won't find trolls in Valve servers?
We cannot stop trolls. Its impossible. So if you aren't willing to mute people so you don't have to hear it, then I don't know what to tell you. Every single server is going to have trolls. We do our best to mange them, but we aren't going to punish people for being mean.
