Internet Censorship in China
by the Los Angeles Chinese Learning Center, which writes:
"Foreign visitors in China frequently complain to me that they could not access certain websites during their stay in China. Indeed, certain news websites, websites related to certain religious organizations (most of them are illegal in China), as well as some pornographic websites are inaccessible from China. Surprisingly enough, our website, the website of Los Angeles Chinese Learning Center at http://chinese-school.netfirms.com is also blocked by the Chinese government. (Through our recent efforts, the site has been unblocked by the Chinese government. Currently, we are offering the service to unblock your website from China)If I ran Google search, I would - just to give the Chinese a taste of their own medicine - block all pages that have anything to do with China - for let us say a month, just to teach them a lesson. Some people do not learn any other way.
In a well researched paper titled 'Documentation of Internet Filtering Worldwide' by Jonathan Zittrain and Benjamin Edelman from Harvard Law School tested approximately two hundred thousand websites by dial-up link and through proxy servers in China. From May 2002 through November 2002, 19,032 websites rendered inaccessible. These sites contained information about news, politics, health, commerce, and entertainment.
