Twitter, Facebook and Youtube have all taken actions to crack down on an alleged disinformation campaign that was said to be originating in China and spread disinformation about the ongoing anti-government protests in Hong Kong.

Twitter announced on 19 August that it had suspended 936 accounts originating from within China that “were deliberately and specifically attempting to sow political discord in Hong Kong, including undermining the legitimacy and political positions of the protest movement on the ground.”

Facebook said on 19 August that it had removed seven pages, three groups and five accounts linked to “coordinated inauthentic behavior” on the Hong Kong protests.

Google said on 23 August that it had disabled 210 Youtube channels for uploading videos in a “coordinated manner” about the ongoing protests in Hong Kong.
