So I've been thinking about this; a lot of the bans that are given out are for swearing, or just obnoxiously speaking, and most of the players who are committing said act won't typically learn their lesson because they AFK anyway so it won't really change anything at all in their life lol
A way to improve this would be by putting said player in a little portion of the map (secluded from players of course) and have them pick up so many pieces of trash.
Just an idea
