BEIJING — Police in China have arrested four people and detained or warned another 81 as authorities crack down on alleged Internet rumor-mongering, state media reported Saturday. Police did not give details on the timing of the actions, Xinhua News Agency said, adding that 16 websites were punished for “weak safety management.” Citing police, Xinhua said that the alleged rumor-mongers “used social network services to fabricate and spread rumors, or forward rumors published on foreign websites.” It added that among the rumors were “predictions of an earthquake in Beijing within two to six days and gunshots having been heard in the west of the Chinese capital.” The latest moves come amid a crackdown on the spread of online rumors, which rights groups have criticized as an excuse to punish people who publish information critical of the ruling Communist Party. Hundreds have been detained in the campaign, while several bloggers have been handed lengthy jail sentences, resulting in a decline in use of microblogs. Dong Rubin, a blogger known for criticizing Communist Party officials, was sentenced to six-and-a-half years in jail as part of the campaign last month, state media said. China tightly controls the Internet, but its online population of 632 million has used messaging applications to push the boundaries of restrictions on free speech. Control measures include the blocking of foreign websites such as Facebook, Twitter and YouTube using a system known as the “Great Firewall.” State media reported Thursday that China is banning users of Internet messaging services from posting political reports without permission, and demanding they promise to “uphold the socialist system.”
Internet companies are required to ensure that users of online messaging services register with their real names, state broadcaster China Central Television (CCTV) cited the government’s National Internet Information Office as saying. Users will be required to agree to “seven bottom lines,” including a vow to “uphold the socialist system,” a euphemism for China’s one-party dominated regime, when they register, CCTV said. Hundreds of millions of Chinese use the Twitter-like Sina Weibo, and messaging app WeChat, among other online services. The latest regulations appeared to be aimed at WeChat, an instant messaging platform that allows users to share text, photos, videos and voice messages over mobile devices.
