I did send the message but nobody is answering, so at least tell me when and where I did break the rules.
You just need to be patient mate, these things take time and Moderators are hand filled already, Hopefully someone with better explanation on the reason for your ban will share it soon, and if it is truly a mistake like you think, you'll be unbanned. from my experience here the chances of it being a mistake are however almost zero.
Yes, but you know it is really nice to be banned without even saying the reason.
