Twitter announced Monday that it would no longer accept advertising from "state-controlled news media entities" after finding that more than 900 accounts originating from inside China have been part of a coordinated effort to undermine political protests in Hong Kong.
The big picture: Hong Kong saw its 11th straight week of pro-democracy protests over the weekend as the city pushes back on what it views as encroachment by the Chinese government on its autonomy. The accounts, which Twitter said were part of a "coordinated state-backed operation," sought to delegitimize the protest movement.
