China kicked off the New Year with another crackdown on the Internet. A government-supported entity—the Internet Illegal Information Reporting Center, tasked with finding and fighting online content that violates the law—began by informing 19 popular Web sites, including Google and Baidu, China’s two leading search engines, that they contain “vulgar content that violates social morality and damages the physical and mental health of youths.” Only a few days later, they expanded their blacklist to 91 sites, including MSN and MySpace, demanding that they all take action to remove the offensive content. By last week more than 1,250 Web sites had been closed down and 41 people arrested. The crackdown singled out galleries of scantily clad women on tiexue.com and videos on vodone.com, as well as Google searches with links to anything that could be deemed racy. On the same day, People’s Daily, an official outlet, posted paparazzi photos of the Chinese celebrity Zhang Ziyi in a bikini at the beach. The Web site of Xinhua News Agency has also run a slide show called “China’s Hottest Babes.”

Hypocrisy aside, calls by authoritarian regimes to curb vulgarity are often a smoke screen for the stifling of political dissent. Iran recently included several sites critical of the government on a blacklist of more than 100,000 pornographic sites, and a study by the OpenNet Initiative, a university consortium that tracks Internet filtering around the globe, found that Vietnam censors politically sensitive content along with obscenity. China’s current crackdown is no exception. Bullog.cn, an edgy Chinese bloglike platform that often irked the Chinese authorities by reporting on controversial events like protests against new chemical plants, is one openly political victim of the current purges. Rebecca MacKinnon, an expert on the Chinese Internet at the University of Hong Kong, writes that “historically in China … the technology used to censor porn has ended up being used more vigorously to censor political content,” and this appears to be the case again now. The thaw in anticipation of the Olympics, in which politically damaging sites like those of Amnesty International and Human Rights Watch were allowed to publish unhindered, may now be nearing its end.
