Twitter and Facebook said Monday they had uncovered a campaign by China to use the social media platforms against pro-democracy protests in Hong Kong. “We are disclosing a significant state-backed information operation focused on the situation in Hong Kong, specifically the protest movement and their calls for political change,” Twitter said in an online post. Facebook said a tip from Twitter led to the removal of pages, groups and accounts originating in China and involved in “coordinated inauthentic behavior” focusing on Hong Kong.
