I don’t think this is oh so terrible. You take a prisoner, who has nothing to do all day anyhow, and put him to work in a virtual environment; playing a game no less. If forced to choose, I think I’d probably rather be playing a computer game, than do manual labor. I mean what’s the difference between forcing a prisoner to do physical labor vs mental work? True, I think double-dipping by having the prisoners perform their manual duties and then later their unofficial virtual work crosses the line in a bit, but overall I think having prisoners do work online is a great idea if applied correctly.
