dude, sorry to break it to you, but there is a reason why there isn't a place for a ban appeal:
Namely becasue there is no such thing. the Mods don't ban you for a simple misunderstanding, they make sure they got good reasons, and bans are kinda permanent. It keeps the server nice for this long, and will keep it that way.
Sorry to say it, but i see your chances of getting your ban reversed slim.
BTW: I'm not a mod, so no juristiction on it, just sharing my experience with you to give you a insight in what to expect
