Thanks for making an appeal, here's the evidence as promised in our conversation last night.
The first case of an obvious lock on through both the wall and when the other player jumps out into the staircase. Before this, the player had crouched all the way up the stairs and into the open door, then you conveniently ran down after he had done so and you closed the door on him before baiting your friend to open it and die. All of this was done without any vision of the other player whatsoever.

A second case of obvious aimlock when this player runs up the staircase.

This one is the longest and is the point where I banned you because I had seen enough. About a minute is cut from this because you were simply standing at the stairs waiting for the dude on the other side of the door to walk in, but you accidentally hit your aim key and locked onto him behind the wall.

Unlike most players who have made an appeal, you were honest in what you did and have accepted all of the evidence that has been presented. That's a positive mark in my book. However, I feel like you came to me as a last resort after you couldn't evade your original ban. It would have been better for you to just make an appeal from the get go instead of trying to use a second and third account. Since you have shown some sympathy and regret for ruining the experience of other players, I would like to hear more opinions from other staff on this.
