When anyone on the server says things in chat that have been deemed too hateful or innapropriate their offending chat will be replaced and be given a warning - after 3 infractions they will receive a chat silence for 30 minutes - if they receive another 2 lifetime infractions they are kicked from the server.

In case of emergency, anyone in this group can use this console command to silence ALL users not in this group until the command is used again:

toggleglobalmute (hit F1 to open console first)
