Well, first brainstorming with some admins/devs yesterday kinda came up with this:
Like with the admin abuse forum back in the days you have to wait 24h after the incident before you post a ban request.
When you post it you need to follow some basic format including time/date of the incident, server, offending player name and proof.
If you miss any of those or the 24h delay the thread just gets deleted.
This will remove a ton of rage ban requests and probably some of the "I don't like this guy so I will try to get him banned for every thing I can find that could somehow be punishable" requests as well.
For urgent matters the ban forum is not the right place anyway, lots of admins can be contacted via IRC and steam so people should make use of that if no admin is available in game.
Same goes for other stuff where people got proof and it's a valid ban reason, they can just go to irc and talk to an admin, present their proof and the admin can post a "Player X has been banned"
thread and put the proof and the reporting player in there.
That way you can circumvent the 24h delay but an admin gets the chance to judge if it is a valid request or not instead of having tons of random ban requests floating around where players just throw shit at each other because they are mad.
Needs some tweaking and especially the go from the overlords but I think this would improve the handling of bans overall and would make the ban section way less painful for all the admins.
