From the Far Eastern Economic Review:
In March 2005, a bold new tactic emerged in the wake of a nationwide purge by the Ministry of Education of college bulletin-board systems. As Nanjing University, one of the country’s leading academic institutions, readied itself for the launch of a new campus forum after the forced closure of its popular “Little Lily” BBS, school officials recruited a team of zealous students to work part time as “Web commentators.” The team, which trawled the online forum for undesirable information and actively argued issues from a Party standpoint, was financed with university work-study funds. In the months that followed, party leaders across Jiangsu Province began recruiting their own teams of Web commentators. Rumors traveled quickly across the Internet that these Party-backed monitors received 50 mao, or roughly seven cents, for each positive post they made. The term Fifty Cent Party, or wumaodang, was born.
