The part of reading rent-a-coder that always depresses me is the rampant contract cheating. It makes me wish that by facilitating that activity and taking a piece of the action, sites like rent-a-coder incurred civil liability to the colleges and universities whose assignments are being bartered.
I'm not quite sure how to work that - maybe sue them as some sort of accessory to fraud, though that would probably first require the university charging cheating students with fraud.
