Meta shut down close to 9,000 Facebook and Instagram accounts, groups and pages associated with a Chinese political spam network that had targeted users in Australia and other parts of the world, the company has revealed.

Meta began investigating in 2019 and its research aligned with several research groups who coined the term Spamouflage, including the Australian Strategic Policy Institute (Aspi).

In a report released by the social media giant on Tuesday, Meta said it had removed 7,704 Facebook accounts, 954 pages, 15 groups and 15 Instagram accounts identified as violating the company’s inauthentic behaviour policy.

About 560,000 accounts followed one or more of the pages, and Meta said the pages were likely acquired from spam operators. The campaign spent US$3,500 (A$5,430) in ads on Facebook.

“This network originated in China and targeted many regions around the world, including Taiwan, the United States, Australia, the United Kingdom, Japan and global Chinese-speaking audiences,” Meta said.
