An example would be auto-mute systems (though now this gets into the issues of should players be informed or not?). I can imagine seamless voting to boot other players as well, but I personally don't see banning as a necessity. Anyways, so for a good Admin system, what I think it should include is:
- Seamless auto-mute system (player is not informed they are muted, and their messages are still shown, but others cannot see).
- Removal to a parallel map (via a vote system, rather than banning, a player can play with other rejects or trolls on their own parallel map, where they can't ruin other player's fun, etc.)
