I actually don’t mind the idea of anti-peen, a “black mark” on your record, kind of like the weird, cancerous growth I have on the tip of my IRL glans. Perhaps like an STD that shrinks your overall Peen length by a percentage. It would be based on how many times you’ve been banned first and foremost.

Even though the OP’s ideas are clever, I don’t think that’s the approach. It shouldn’t be collectible and it could be invisible to outside users. Trust me, you wouldn’t want this **** Log in to see images!
