It's unfortunate accidents like that happen, but as far as clearing them, there isn't a public way to do it. I agree it's kind of a scar that's always there, but you shouldn't feel bad about it. If it helps, even VSTF members today were blocked before in the day.

You can try asking Staff about it in Special:Contact/general but they probably can't oblige to help clear it.
