I was banned a really long time ago, some guy used aim bot and I turned on some kind of hack too, and received perma-ban. Then I got unbanned with a release. And then ban again.
My point is that it was a really long time ago, and the reason of banning is to keep hackers away from the server. It was a "long enough" time ago for me to not hack ever again.
Just saying, unban if you want, if you don't then it's nothing, perma ban for hack is fair after all... As you want it.
