Lots of snapping here. I encourage you to slow down the playback speed to 0.25. The snaps are much more obvious at slower speeds.
The tells with a lot of players like this are slower, tank like movements and slow reaction times when actually getting shot. They are also slow to get health or throw down medkits. Often times they also jump out of windows without parachutes as well. Although he is firing in what might appear to be controlled bursts in this example, you can see very obvious snaps, especially when you slow down the video playback.
Thank you for your report, this player has been banned.
