AFK report
Yeah, Ive got one dude today and sent a random report (dont remember what ive used, but if they really look at logs theyll understand).
Ask everyone in the map to report him under “Botting” as maybe they’ll review it.
I have had someone do this on a couple teams, and even the other team was willing to report him because it hurt their fun too. Even if you are up 200, its no fun if you opponent just lays down and dies. People pvp for the challenge.
