Spectator Mode

I think I speak for all of us here, but I for one find it rather irritating when somebody has gone AFK and you're a guard so you have to search every cell, one by one, to find those few AFK players who are delaying the next round about to start. I believe that it would be a good idea that if somebody had been AFK for more than 5 minutes, they would be set to a team called spectator mode. This would work the same way as if you had died; you can only spectate prisoners to prevent ghosting guard's positions. It would surely help make the improve the wonderful gaming experience that Unknown Gaming provides for players all across the world.
