The 50 Cent Party are Internet commentators (网络评论员, 網絡評論員, wǎnglù
pínglùn yuán) hired by the government of the People's Republic of
China (both local and central) or the Communist Party to post comments
favorable towards party policies in an attempt to shape and sway
public opinion on various Internet message boards. The commentators
are said to be paid for every post that either steers a discussion
away from anti-party or sensitive content on domestic websites,
bulletin board systems, and chatrooms, or that advances the Communist
party line.
