Right, it* can be caught looking at behavior I would guess, but as long as u are bit a bit careful that is fairly easy to hide then.
As others have pointed out, doesn't this encourage (even to atleast trying) multi? And will it not reward the current multi-cheaters that get away with it?
It would be something you could live with, but I would like this to be addressed, please. I would like to see a thought process around it. Possible benefits, and possible consequences?
