Maybe it is just a state plan to keep an eye on the yakky dullards amongst the citizenry:
New rules by a Chinese government-backed Internet group maintain strict controls over the country’s bloggers, requiring them to register with their real names and identification cards. The guidelines from the Internet Society of China (http://www.isc.org.cn), a group made up of China’s major Internet companies, contradict state media reports this week claiming that China was considering loosening registration requirements for bloggers to allow anonymous online journaling.
Well, fat chance of that. Given what might be called “unhealthy content” by a blutocrat working in a dictatorship one can only presume that the search to squash it is really just a great make work project. Which may make it more honest: in dictatorships, people are paid to idly read the web while in the free world people are paid while they idly read the web.
