Yitahutu, one of the largest online communities in Chinese universities, has disappeared from Chinese cyberspace.
This politically provocative online community saw its influence grow beyond its own Peking University campus to become a national information network.
Because of Yitahutu's self-organizing, bottom-up editorial control structure, similar to Slashdot, the editors cannot be held responsible for what appears on the front page. Therefore, the Internet police found their only solution was to close the whole site down.
On September 13, The Beijing Communications Administration issued a notification that Yitahutu BBS is permanently closed. In the meantime, many Chinese BBS sites announced that it is forbidden to discuss YTHT on their systems. And the YTHT domain name itself has been entered into the filtered keywords list, including on the Chinese search engine, baidu.
