Don't say IPs
=============
Messages like "hey join my server 213.34.231.23" are automatically blocked... and another message is printed instead. :-P
Or, you can choose to just ban violators by setting cvar ip_banviolators to 1 and ip_banminutes to how many minutes the violator should be banned. 0 is permanent, 5 is default.
