Info current as of early February, 2005. Police in the southern Chinese city of Guangzho arrested 29 people in connection with an Internet prostitution site that documented call girls in 20 Chinese provinces and regions. The site called "playchina" or "xiyouzhongguoll" which had 15,700 registered users, has also been shut down, according to the Information Times. After police discovered the site in October, a two month investigation resulted in the arrest of 29 domestic webmasters involved with the site which was run from an overseas server.
Users of the website were given detailed information on call girls throughout China with over 65,000 photos posted on the site, it said. After downloading the entire site's contents, investigators found themselves with a one-meter (one yard) high stack of printouts.
In an Internet clean up campaign that began last June, Chinese police have shut down nearly 1,300 websites deemed to be spreading harmful information including pornography. The number of Internet users in China will hit 134 million by the end of 2005, consolidating its position as the second largest market in the world after the United States.
