Although the player CHETKIY_GUSEYN has already been marked as clean, I would like to present some new evidence recorded on TBG 24/7 lockers server.

At 3:34 time mark, he goes inside enemy base and attack a prone player without any information that someone was there, no 3D spot by fire sound or any else on the map, it is strongest evidence that CHETKIY_GUSEYN was using Wall Hacking. Although I do not think he was using Aim Assist or found any evidence on video recorded.
