Player rank 15 on leaderboards at the time of this post is hacking, the player’s name is all rectangles/squares (the type you get when characters or fonts cannot be used).
I played with him 2 games back to back, he picked Crow and proceeded to shoot the ground until suddenly the monster was dead, wherever it was. He did this in both games I had him/her in and won the game in seconds. He had 8 or 9 win streak at the time.
I wanted to report his steam, but since you could only check someone’s steam profile only at players joining screen, I could not, since he left afterwards (probably because he knew if he stayed, he was getting reported)
