Hello, came across this player on our server today, noticed he hit alot of odd shots during the game and choose to spectate him and noticed that it seems that he has aim-look, you'll see multiple situations in the clip where he snaps onto players.

Looks like you found how to report. Just need to wait. Just a note, i suggest not talking in the chat while spectating someone.
