Long-time member, and I got banned while playing?

[[toj.cc]Flame]

I'm sure this is a mistake so I'm hoping someone can clear it up for me. I haven't played in years, but I recently started getting back into CSS and was super excited to see my clan was still around. I'm an OSGN member and have played on this server for a long time. So I was really surprised to be kicked and banned from the server tonight for "general hacks and cheating" or something like that. I've never hacked a game in my life. Can someone clear this up for me so I can play again? Thanks!
