This is a very simple community and most people here who have received if at all any warnings have generated them from the "Leaving/Returning Topic", its hard to break the rules when all there is to discuss is art and not general discussions.
One of the issues I've faced as an admin of previous forums and watched others deal with identically, is that the admin and mods become too polite about banning. Take a month off or three and return and to disrupt the community some more, eventually this cycle grows into half the community and overruns it: members leave, too many warnings to go around, and the forum closes.
If you are banned here, it will be three years till you can mature significantly or permanently. You should not be getting banned unless you are caught for theft, are intrusive toward other members or are disruptive. If are you banned for any of those reasons, then most likely a majority of the community will not want you to return.
When the community has that sigh of relief that someone is gone, that's what I'm talking about.
Being banned does not mean reaching full bar either, this is not a game.
I will look into removing warns collectively once a year so people do not reach full bar or become paranoid once they do reach a certain limit. For some cases, you will only be banned a month but that can be discussed among the mods.
Being banned will result in both forums.
