the player appears to automatically focus on the zombies when he holds down the left mouse button. I watched the demo several times and I am of this opinion. Let the demo be watched by someone else and have their say. at 11:30 a.m. when he becomes a zombie and holds down the left button you can see how he automatically turns to people and focuses them. I turn it off "knifes blinks" as a proof for that because now have cooldown. when he runs after a player with the left button held there are some glitches or idk how to say it (10:00) ,seen at the beginning of the demo. This is my opinion for now.
I think everyone deserves a second chance and the player will be unbanned. The player will be monitored for such situations. Dont use again hacks, its just a game.
