There isn't voice chat. Just a chat window that scrolls by as the kids troll. There is a mute feature just /mute <playername> which as someone stated earlier people will report you for muting. I've resorted to just /mute all and that way no chat from anyone. Not really an option if it is 3v3 or 5v5. Once again, another reason I play against bots. I really don't need to know how many 11-13yr olds have fucked my mom.
