Facebook Inc said on Friday it had deleted more accounts originating in Iran that attracted no fewer than one million US and British followers.
It said this was its latest effort to combat disinformation activity on its platform.
The social media company removed 82 pages, groups and accounts on Facebook and Instagram that represented themselves as being from American or British citizens, then posted on “politically-charged’’ topics.
Topics such as race relations, opposition to US President, Donald Trump and immigration, Facebook’s head of cyber-security policy, Nathaniel Gleicher, said in a blog post.
In total, the removed accounts attracted more than one million followers.
Facebook said: “The Iran-linked posts were amplified through less than 100 dollars in advertising on Facebook and Instagram.’’
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 action follows takedowns of hundreds of accounts linked to Iranian propaganda efforts by Facebook, Twitter Inc and Alphabet Inc.
Social media companies have increasingly targeted foreign interference on their platforms.
This follows criticism that they did not do enough to detect, halt and disclose Russian efforts to use their platforms to influence the outcome of the 2016 US presidential race.
Iran and Russia have denied allegations that they have used social media platforms to launch disinformation campaigns.
