If Theymos himself banned you, you are pretty well screwed. If a Moderator bans you, an Admin can give the ban a second look using their own judgement. If their judgment banned you in the first place, you are probably done.
Well I don't know who banned me, but I assumed it was Theymos because the e-mail address I was given to appel contains @theymos.e4ward.com . Now that you mentioned could have been a moderator as well.
I deserved to be punished because I infringed a rule, however what really pissed me off is that no one gave me any explanation or answered my e-mails, and I apologized and ensured it would never happen again.
I did something wrong, but at least I recognized it and wanted to work on it.
Please keep that in mind and consider it. What do you say?
