Washington: Facebook Inc said on Friday it had deleted accounts originating in Iran that attracted more than 1 million US and British followers, its latest effort to combat disinformation activity on its platform.
Social media companies are struggling to stop attempts by people inside and outside the United States to spread false information on their platforms with goals ranging from destabilising elections by stoking hardline positions to supporting propaganda campaigns.
The fake Facebook accounts originating in Iran mostly targeted American liberals, according to the Atlantic Council’s Digital Forensic Research Lab, a think-tank that works with Facebook to study propaganda online.
Facebook said it removed 82 pages, groups and accounts on Facebook and Instagram that represented themselves as being American or British citizens, then posted on “politically charged” topics such as race relations, opposition to US
President Donald Trump and immigration, Facebook’s head of cybersecurity policy, Nathaniel Gleicher, said in a blog post.
In total, the removed accounts attracted more than 1 million followers. The Iran-linked posts were amplified through less than $100 in advertising on Facebook and Instagram, Facebook said.
While the accounts originated in Iran, it was unclear if they were linked to the Tehran government, according to Facebook, which shared the information with researchers, other technology companies and the British and US governments.
The Iranian UN mission did not immediately respond to a request for comment.
The action follows takedowns in August by Facebook, Twitter Inc and Alphabet Inc of hundreds of accounts linked to Iranian propaganda.
The latest operation was more sophisticated in some instances, making it difficult to identify, Gleicher said during a press conference phone call on Friday.
