Maybe a joystick user? most of us gets confused about allegations of sg because of a joystick user.
I actually dueled with this guy a few times back in August, he isn't a joystick user because a joystick can not match his glitching speed and aim.
He definitely is faster than the average player but that is not achieved by the way he glitches (no c glitch after crouch), my guess is that he changed his game's speed to x1.1 or x1.2 judging by the jumps he made at 0:04 and 0:08.
I never made a case about him since /checkspeed never gave a valid reading (apparently that script never worked properly either way), I figured his low latency to the server is influencing his 'position' and animations/packets sent to the server.
