When you shoot with the makarov while proning it gives that error-pop up to other players. This happened in a firefight and I was accused of hacking, luckily I got an in-eyes video out of this situation.
It seems to be the same problem that persisted with the amphibia S, which caused the same dialog to pop-up for other players.
