I've been loggin to my account like 2 days ago, and I have noticed, that it's banned for nothing. I have written a ticket, describing my prob, but I'm waiting third day to resolve it. I have got some auctions set, and I'm gonna lose some serious gold just for being banned for nothing. -.-
some bans might happen as a result of mistakes, but to tell directly that it's banned for nothing is something which can be untrue. I'm not going to judge you, it's up to the GM.
The only thing which you can do is waiting. The GM's are pretty busy with a lot tickets right now, but they will reply on your ban appeal if you wait patiently. If you want, you can track your ticket progress here : contact us - my tickets
(Although i am known by the GM's and some of these like to tease me to reply after a week because they know that i am patient : / )
And about the auction house, you have 13 days time period until it erases itself. So still enough decent time left.
