Maybe add an option for muting a specific player, only for your own pc.
/mute already is for totally muting a specific player, and can only be used be the ruler of the room, I guess.
The new option should be /silence [player name].
So if I for example type /silence SomeJack*ss, other players can still read his tekst, but I won't get annoyed by it.
It is not all about swearing, some people really try to communicate in-game. Sometimes spammers make this impossible.
Also don't tell people to deal with swearing and sh*t (not that I care), some people really can't take it for a specific reason (too young, some religion, etc).
Don't go "Ha! Geeeuuuy"-ing me for having respect for some people.
