I usually do not get involved with public ban appeals, as there is a correct method of going about submitting your ban appeal. But, I am going to respond to this one as you are questioning the integrity of the PBBans community.
First off, he was kicked for a cvar........a well known, and very, very confirmed cheat cvar. There are only two ways to get this cheat cvar, using the illegal program that utilizes this cvar, or by putting this cvar in your config yourself (either by typing it in or by using someone elses config).
Now if it was a situation of using someone else's config, then the ultimate bottom line is that you are responsible for the editing of your config as Stymie stated. If you change something in your config, you should know what you are changing or at least find out before you change it. You ultimately can not trust other people in this world, and you will be held repsonsible for what shows up in "your" config.
But the problem here is not someone else's config file. As brought to light by RodeoBob's post, you did in fact appeal this ban. And in the appeal post, you stated what happened to you. You said it was a pb updating issue. You updated PB and it took care of the problem. Then you asked them to take the ban away because you would never, ever cheat. The problem lies in that you never stated that it had anything to do with someone else's config. And what you were ultimately banned for could never have been caused by an un-updated pb software issue.
So in light of all the evidence given, your ban is valid. You have no grounds what so ever to come to PBBans and question their trustworthiness or to bash PBBans. There was no SS involved in the final result, so that could not have been faked. There was no admin submitted evidence, so a misceivious admin could not have sabotaged you. This violation came straight from the server logs, which are streamed straight to PBBans. When you were kicked, PBBans got a copy of it. So, I am sorry that you have been caught, but next time save yourself the embarrassment and don't attack the integrity of PBBans.
