China‘s largest microblogging service has introduced a code of conduct to restrict the type of messages that can be posted. The new move from Sina Weibo, seen to be the latest attempt to censor social media, comes after local authorities criticised the posting of “unfounded” rumours on the network. Under the new rules, users start with 80 “points” which can be deducted for breaking the sites code of conduct, and repeat offenders risk having their accounts deleted. The site has also developed a “community convention” clearly outlining what type of postings are unacceptable on the site.
