Gao provisionally rates every bit of text on a scale of 1 to 10 before he posts it. His initial "sensitivity" rating is usually a good indication of the time the posting will last on the public area of the news site. A "1" is something totally unthreatening, while a "10" would be lucky to get online at all and would remain for just minutes if it did.
"Look at this one," Gao says, pointing to another comment made by a user on Sina.com some hours before. "It says, 'Why arent we protesting in the streets against this war like other countries are doing and like we did after the U.S. bombing of our embassy in Yugoslavia?'" "Its been there for several hours already. Surprising it would be allowed to stay so long. I mean, this isnt just foreign policy chitchat; this is a call for people to go out into the streets. This is an eight or a nine, certainly. Very dangerous."

I wonder how much of it is because of Chinese-language specific internet content?
