The Cyberspace Administration of China (CAC) has designated a special group from its Beijing arm to visit social media app Douban, according to a statement from the internet watchdog on Tuesday. The regulator said the team will be stationed at the company to rectify “serious online chaos,” without elaborating further. The move comes four months after Douban received a RMB 1.5 million ($235,000) fine for “unlawful” release of information in December. The company, which claims around 200 million registered users, is among a group of Chinese apps including Weibo and Tencent, which were fined for posting “illegal” content. But it’s rare for China’s internet watchdog to send on-site teams to companies. [CAC statement, in Chinese]
