Well, I can't get a current punishment system at the moment, so for now we are going to have to stick with this.
Each user is allowed 3 warnings. Once you get the final warning, it's a temporary ban. Here's a list showing exactly what is a temp or perma ban.
Posting Inappropriate links (2 warnings)
Spamming in the wrong place (1 warning)
Flaming (1 warning)
Trying to sell something (2 warnings)
Posting illegal items (
Temp Ban)
Hacking (
Perma Ban)
Raiding (
Perma Ban)
Posting Inappropriate Images (2 warning)
Threatening the forum (
Temp Ban)
Mod Power Abuse (1 warning)
Well, that's all I can think of at the moment.
Let me know of any more needed to be added!
