I've never been banned/put on probation/whatever from the site, but I'll answer OT for what i first thought the thread was about before i read, which was highschool:
I got suspended from high school for turning up to my year 12 (final year of highschool, sub in your local version) photo day with the most dodgy, dodgy mohawk ever that two guys in the boardinghouse paid me 30 bucks to be allowed to give me.
I don't have photo's handy, but to give some idea, I had hair about 1.5 inches long that they just shaved except for a strip about 2-3 inches wide (and markedly off centre) down the middle of my head. It looked truly awful.
Posh private school, too. The type with expensive tuition to pay for the replacement costs of all the silver spoons up their asses. It was classic.
