Demos will be uploaded soon.
Edit:
@fNNDemo 1: This is the demo that made me suspect you the most. It started as a cage day and everything was going normal, but then 1 T escaped to the football field. You seem to have a very good 'eyes' and assuming you saw him but you couldnt go straight at him as there were few Ts on your side. After few seconds you left your side (knowing that none can escape from your side with your wallhack as all of them reached the cage without you even checking the cells). While you were on top of the cage and trying to go kill the missing guy, you heard him stab the vent, but it was far and he had enough time to hide near the door or trampoline. What was weird is that when you entered the football field, you did not check the right side, knowing he wasnt there. You went into trampoline, aiming exactly at his spot. Not even checking the sides, looking straight up at the exact position. Once you killed him, you took a quick peek at the vent, pre-aiming at a T inside the GR trying to get guns. He did get the guns and you heard him, so you tried to kill him while shooting the vent. Then, the T disappeared, you took cover for a second and tried to kill him again. Whats strange was how you took a fast peek, thinking he would return and shoot you, but using your wallhack, you knew he wouldnt come. A normal experienced CT would wait there or even throw a nade. As you knew they were going outside through the other door, you went back to the cage, aiming at the entrance near the cage as there was 1 approaching. You shoot him few times, but run out of bullets. But you knew he run, so you switched to USP and finished him off.
Demo 2: The demo starts with a HNS day, there was a T who shoot few bullets with a mac10 from the football field, what I found weird was how you kept aiming there. Then the day starts and 1 T throws a nade at you and quickly goes dark room, you follow him and kill him outside the darkroom. Once you killed him, you open the dark room door and pre-aim at a hidden T behind that box. After that, you threw a nade at the cell near the vent cell, as there was a T hiding there- you were hoping to get damage so you can go there but u did not damage him. Whats more weird was the fact that you did not use that nade inside the dark room, as it is the most common place for prisoners to hide in, you "randomly" chose to throw it to the cells there... You say you are very experienced, yet you tried to heal using the healing stations in a hide and seek day, which is something you cant do. 99% of the players know in this in the server. You hear someone breaking the vent, notice how you jump to get a peek at him. Apparently, you decide to leave this vent T, when you can easily nade him by taking a new set of guns. Not so experienced now eh? Also, you never check the sideways of an entrance which is really a bad idea, and shows lack of experience.
Demo 3: I cut the demo to make it shorter. 2 weird things attracted my attention here. The way you check the KZ, you checked the race area but not the elevator area as you magically knew none was there. The second thing is how you entered the dark room, and killed that hidden T while walking. Walking and killing that T may seem normal, but according to your pattern, why did you not walk to that first box and shoot there? Also I noticed another thing, when Dave said something about you wallhacking, you became more aware and surprisingly started checking the sideways (e.g. the box on top-left in the entrance of the dark room)- perhaps to act like you dont use wallhack?
I didn't have much time to record more demos as I had to go offline, but your screenshot could be clean as you might have quickly pressed the toggling key which turned off the wallhack just before the screenshot was taken. To prove that his might be possible, Demo 4 shows the time delay.
