If you break the rules, you get a ban/kick as a punishment, but since all the rules are the same in their importance, the punishments are the same, just depending on how many times you do them.
1st rule break: kick, then return
2nd rule break: 24 hour ban, then return
3rd rule break: week ban, then return
4th rule break: month ban, then return
5th rule break: permanent ban, and return only if the administrator allows you to do so.
The rules and the punishments should be clear and would be enforced most of the time, with exceptions made on administrator's or moderator's decision.
