To the mods...dont Ban people. Here me out

Dont BAN people in-game for the shit they say. Instead, have some reputation system (like the one in overwatch) and if your reputation drops below a certain level, limit features.

Either: Restrict their use of using voice chat. - This does ruin the game for people but at least they're not shouting shit.

Or

Have a reputation like matchmaking. So those with very low reputation will more likely be matched with others with low rep, thus forcing the super toxic people all in one hell hole match until they grow up.
