You know your signature was over the line. I was about to have it removed and give you a warning, when I came across your profile and saw you claimed to have 2100+ vouches. I'm fairly sure you don't even have 1% of that.
As for the signature, that was over the line. When allowing it jokingly, we are opening the door for all sorts of lame excuses.
It's wrong, You know it is. Your signature rights have been revoked. You may dispute this once you are unbanned.
See you in two weeks or until you can somehow conjure up these 2100+ vouches I missed.
