What's funny is that the defending line of thinking is a type of thinking that is influenced by survivor bias. If we accepted that defense, anyone not currently banned for cheating could just use that defense. Ignoring hypocrisies, the points mentioned boil down to "GB Mad". The situation occurred after the tryout because we had been investigating and suspecting you of cheating for quite some time. You proceeded to mouth off, explaining how you "shit on us" in similar mannerisms. That was reason enough for a blacklist, but in fact, you were blacklisted before the tryout began. We checked docs afterward and noticed your name on the list while in the process of adding your name to it. Given the proceedings of this event, it checks out, seeing as toxicity is looked down upon.
On to the videos: The first thing I noticed was at the third video, at 12:30, instead of moving to cover where I could have gone, he walks straight up the stairs, all the while staring at me through the floor. Pay attention to his view for the following 15 seconds. Very strange behavior, especially after the previous awareness he's displayed, he chooses to deliberately stare at the ground while walking up the stairs. The instinctual crouch jump, might be irrelevant, but could have come from him not expecting to be shot. This is especially notable, as he chooses to ignore potential flanks, while staring at the ground. Additionally, the same video, at 3:58, the tracking there is pretty blatant. This is a major oversight by him, thinking that you could see through the shelf at that distance from it. Also, neither player shot, until there was established sight. Perhaps he committed to this phantom line of sight, but not enough to fire his weapon. This is clip is even more damning when you watch the GAP TEST video. Game sense it's much of an excuse here, since his opponent stood still long before he rounded the corner of the supposed "gap".
EDIT: Upon review, of all of the SCs of the instances and recreations, the instance at 3:58 is dismissable. Once again, same video, time stamp is 5:08. He displays very strange behavior, before giving himself away. To elaborate, he sees his opponent proceed behind the (small) shelf. He continues to suppress ONE side of his opponent. Coincidentally, the one side his opponent is on. This is strange, considering his display of awareness, he should at least be aware of an obvious flank. His opponent could take literally one step to his right and peek him on the other side, but he completely ignores this. He also pushes into the open, and after finally pressuring him enough, his opponent peeks his left, followed by a jump peek on the right. While this happens, he repositions, at the exact same time his opponent jumps, to peek him as he lands. While he swivels to peek him, he proceeds to swing far enough to shoot me in the chest, then immediately head shot his opponent on the next shot. You can hear me say "he hit me in the chest" which is also displayed in logs in a following video. An obvious explanation could be smooth aim, seeing as he, well, aims smoothly. This also explains why I got targeted.
Also, people want to read everything you have to say. So far, all I've seen said in regards to anything posted here is the barrel through the box, and that trusted players have said that you were a non cheater (?) in the past. Both points, of which, are moot. Both videos showcase the opponent not being visible by any means through the shelf. Regarding the "history" of being a "non cheater", it not only doesn't make sense, but let's say for an instance that we heavily considered/accepted this. This would be that personal history is heavily valued subsequently, in which, you have much of being a cheater. That being considered, it seems a little backwards to stand by this point.
EDIT 2: @Torch's response is well put, and I have to say I agree.
I will not be adding a -1 or +1.
