China’s media regulator has ordered live-streaming app Kuaishou and popular news aggregator Jinri Toutiao to clean up content on their sites -- the latest in a string of moves by the Chinese government as it seeks to remove what it calls “inappropriate” content from the net.

In a public statement, the State Administration of Press, Publication, Radio, Film, and Television said that all “vulgar, violent, gory, pornographic, and harmful” content must be removed from both sites.

Reviewing and reducing uploads will be a huge task for the sites.
