Twitter announced on Monday it has purged over 200,000 for violating the social networking platform's terms of service.

The online news and social media network believes these accounts are part of a covert Chinese communist party’s (the CCP’s) operation targeting the Hong Kong pro-democracy protests.

Twitter says it is also prohibiting ads from state-controlled media companies.

The social media platform states it has purged an extra 936 core accounts believed to originate from China. The tweets from these accounts are spreading political disharmony in Hong Kong by undermining the legitimacy and the views of the pro-democracy protest movement.

Both actions are part of Twitter’s endeavor to control malicious political activity, following criticism that it is facilitating election interference globally. The popular social media platform has also been condemned for accepting money for propaganda ads from state-controlled media organizations.

After a tip from Twitter, Facebook conducts its own investigation and reveals accounts linked to individuals connected to the Chinese regime. It has removed three groups, seven pages, and five accounts, and those depicting protesters as cockroaches and terrorists.
