Yep, i suggested exactly this to them (suggested by support screen, not here tho). If the person stay a month without breaking rules the gauge start decreasing...and if it gets full the user will be temp unable to post until it decreases (1 month). Would be an very simple, automated way to help mods controlling those more exalted users, lessening the load of work mods have to do and, over time, it might have users actually end moderating themselves since they will know if they need to stop trolling/flaming for a while, until gauge decreases a bit, or they are safe from getting a temp suspension.
