OK, so the old mute system goes like this: you say a bad, you get muted, you say it a few more times you get banned for 24 hours. I think there's some room for improvement
I call it the "six strikes and you're out".
"Strike one" You get a warning that says- WARNING IF YOU CONTINUE TO SAY THIS WORD YOU WILL GET MUTED
Same thing for strikes two and three except you get muted on the 3rd one.
Strike four you get muted for ten minutes
Strike five muted for fifteen minutes
Strike six banned for 24 hours.
I think this system would help weed out the players who are just messing around from the ones that are actually bad.
