All admins have access to sourcebans and we can edit our bans on there. Honestly, this should not be a big deal. He got it early and left but wants to have it again albeit this time it will be different due to more servers and more rules.As I wrote earlier, there was a reason for the ban (bad language, IIRC) but it only listed as "bad" because I didn't use quotation marks in the command.
Dunno about today, but not all admins didn't have access to Sourcebans. That, and because nobody cared, is why it was never fixed.
I have played with him and, mostly, he kept to himself and stomped on a pub because he is good. Only things I remembered him saying was a few binds when he dominated someone.
