Reuters have reported that China is cracking down on users who upload content to what is China's Twitter-alike Weibo and internet video sites like Youku and Renren.

China's State Administration of Press, Publication, Radio, Film and Television states that all those who wish to upload content must now do so under their real name as a way to police "vulgar content, base art forms, exaggerated violence and sexual content in internet video having a negative effect on society."

Commentators are seeing this as a way for the government to crack down on anti-government content. The use of Weibo and internet video sites like Youku and Renren have often been used to upload critiques of the government with evidence of problems like corruption and abuse by government officials.
