Requires users to register with real names, follow Chinese law
China's biggest microblogging service, the Twitter-like Weibo, has mandated a new "user's code of conduct" for its estimated 300 million members. The new rules on user interactions restrict the type of messages that can be posted compared to previous guidelines. Prohibitions include revealing national secrets, threatening China's honor, promotions of cults or superstitions, calls for illegal protests or flash mobs, rumor distribution, or personal attacks. The move comes after the Chinese government ordered Weibo and its competitors to ensure all members registered their real identities by March.
