Twitter is being criticized for running promoted tweets by China’s largest state news agency that paint pro-democracy demonstrations in Hong Kong as violent, even though the rallies, including one that drew an estimated 1.7 million people this weekend, have been described as mostly peaceful by international media.

Promoted tweets from China Xinhua News, the official mouthpiece of the Chinese Communist Party, were spotted and shared by the Twitter account of Pinboard, the bookmarking service founded by Maciej Ceglowski, and other users.
