I just want to throw in that I think the only justifiable permanent one is VAC ban which takes your ID off the protected servers completely.

That means he wouldn't even have the chance to enter the server in the first place.

To be banned from many pubs doesn't really prove that hes a hacker, but just that the server admins disapprove of his game style whether hes too good or just annoying to them.

Even I go around playing in random servers and sometimes get banned because the admins are iffy about me but that doesn't justify that I hack.

tl;dr Hes's an OG 5 Dig and the server admins banned him instead of VAC. I'm just on his side for this.
