I agree. Paraphrasing Clarke, any sufficiently skilled player is indistinguishable from a cheater. And this is the charitable version too. Often participants just use whatever to hurt the other party - if they are not able via game mechanics, they will resort to reporting. It's how players are raking up Griefing reports in Rainbow 6 Siege's last update. I barely played some hours, and never griefed, yet still got some.
