Need to know why I've been banned?? (Ban Ended)

[Pendragon1989]

I understand "your account, your responsibility" And of course, I had a friend over for a few days, and I let him play LFS. I would like to know what it was that he did to get me banned? And how long of a ban? And perhaps how I can get it removed/reduced? I've been playing on TC for many years, never so much as a kick, much less a ban.
