If you were to log into EMC using your iPhone with MineChat and be in an afk room for a mob farm, would you still be counted as a player and therefore activate the farm? Or do I physically have to have a Minecraft client opened to the afk room? Basically I'm setting myself up there and making my iPhone afk there so that I can do other hardware-intensive things on my PC without having another client opened cutting on my resources.
When you see a player in town they have a body and are hovering over the floor at spawn. It might count since as far as I know you physically exist in the game (you can still die or be affected) while on mine chat so I could say yes.
