without any kind of timeframe then you were probably banned on a permanent basis. If you did not present any basis as to why you were banned in error then it is unlikely that you will be unbanned on an immediate basis although if you come back in the future then you *may* get unbanned if you ask nicely and demonstrate that you learned your lesion.

What about the other part where it said what you were banned for? As far as I know, its not possible for an admin to ban someone without filling in a reason. If you check the other people with threads about their ban, all screen shots say, "for insubstanial posts + signature" or "spamming" or something similar.

As far as your appeal that was sent to Theymos, it will be read. It might take a day or two, but it will be read. If you don't recieve a response, that means the appeal is denied and you should just wait out your ban to avoid ban extension. If you weren't give a specific amount of time until your ban expires, that means its permanent. However, if you don't break any rules ie don't ban evade, you can appeal to have the perma ban lifted in 30 days with a decent success rate.
