What I pieced together from what you have written was you were banned a long time ago for something and are not sure what for. As for how you got unbanned we do not unban anyone unless they request unban on the forums. If you were indeed banned I will be able to find out why, however you need to tell me when you were banned and what name you were using at the time. And if you were banned it was not for no reason and you know this. If you wish to follow this up further please PM me and I attempt to do some research for you. If it was indeed a long time ago it may be difficult to dig up the information. I am not sure why it would matter to know such information now though.
