I accuse him of: spawnkilling, spawncamping, laming, autoaim, wallhack and likely hacked high ping.

The attached demos show symptoms of all mentioned behaviors.
I would request someone ban him for a month or so (as per autoaim+wallhack).
P.S.: On harbortown map, when he's just standing still for a long time in the spawn, his cursor suddenly moves but stops when it passes the doors. I imagine autoaim worked it's way through the doors.
Nothing happens in the demo after that, he just stands still.
