China seems to now pay people per porn website discovered and reported. Being cynical, I wonder to which extent this solution might be cheaper than hiring them as full-time employees for the Great Firewall. A future law and economics study?
In terms of human rights and liberties, well, using people to report websites (free of charge) is a common procedure in most countries. UK does it with Internet Watch Foundation; France does it with the Internet Gouvernance website and system, etc... None however when as far as paying them! The question is probably how the prospect of being paid could affect the "objectivity" (if any) of the person's appreciating the contents of the website. As usual, how the information reported is used by Government or non Governmental agencies is crucial as lack of transparency promotes censorship and violation of human rights.
