From Nicholas D. Kristof's NT Times op-ed article "Slipping Over the Great Firewall of China:"
Then there is the Internet.
It’s true that the government censors critical Web sites and closes down troublesome blogs. Yet there aren’t nearly enough censors to manage the job, and many Chinese are quite adept at technological ladders over the Great Firewall of China. Objectionable posts are deleted by censors, but then are quickly reposted on 50 different platforms.
This is a cat-and-mouse game in which the spotlight is usually on the mice when they get caught: China has more Internet commentators in prison than any other country. But the larger truth is that the mice are winning this game, not the cats.
