Today we removed multiple Pages, Groups and accounts that originated in Iran for engaging in coordinated inauthentic behavior on Facebook and Instagram. This is when people or organizations create networks of accounts to mislead others about who they are, or what they’re doing. We prohibit coordinated inauthentic behavior on Facebook because we want people who use our services to be able to trust the connections they make.
As soon as we detected this activity, the teams in our elections war room worked quickly to investigate and remove these bad actors. Finding and removing abuse is a constant challenge. Our adversaries are smart and well funded, and as we improve their tactics change.
To ensure that we stay ahead we’ve invested heavily in better technology and more people. There are now over 20,000 people working on safety and security at Facebook and thanks to improvements in artificial intelligence we detect many fake accounts, the root cause of so many issues, before they are even created. We’re also working more closely with governments, law enforcement, security experts and other companies because no one organization can do this on their own.
We will update this post with more details when we have them, or if the facts change.

What We’ve Found So Far
By Nathaniel Gleicher, Head of Cybersecurity Policy
This morning we removed 82 Pages, Groups and accounts for coordinated inauthentic behavior that originated in Iran and targeted people in the US and UK. The Page administrators and account owners typically represented themselves as US citizens, or in a few cases UK citizens — and they posted about politically charged topics such as race relations, opposition to the President, and immigration. Despite attempts to hide their true identities, a manual review of these accounts linked their activity to Iran. We also identified some overlap with the Iranian accounts and Pages we removed in August.
Our threat intelligence team first detected this activity one week ago. Given the elections, we took action as soon as we’d completed our initial investigation and shared the information with US and UK government officials, US law enforcement, Congress, other technology companies and the Atlantic Council’s Digital Forensic Research Lab. However, it’s still early days and while we have found no ties to the Iranian government, we can’t say for sure who is responsible.
- Presence on Facebook and Instagram: 30 Pages, 33 Facebook accounts, and 3 Groups on Facebook, as well as 16 accounts on Instagram.
- Followers: About 1.02 million accounts followed at least one of these Pages, about 25,000 accounts joined at least one of these Groups, and more than 28,000 accounts followed at least one of these Instagram accounts.
- Advertising: Less than $100 in spending for ads on Facebook and Instagram across two ads paid for in US and Canadian dollars. The first ad ran in June 2016, and the second ran in January 2018. We have not completed our review of the organic content coming from these accounts.
- Events: Seven events hosted. The first was scheduled for February 2016, and the most recent was scheduled for June 2018. 110 people expressed interest in at least one of these events, and two events received no interest. We cannot confirm whether any of these events actually occurred. Some appear to have been planned to occur only online. The themes are similar to the rest of the activity we have described. [Updated on October 26, 2018 at 1:30PM PT to provide additional information on the seven events.]
Our elections war room has teams from across the company, including from threat intelligence, data science, software engineering, research, community operations and legal. These groups helped quickly identify, investigate and evaluate the problem, and then take action to stop it. They will continue their investigations, including any additional information we get from law enforcement, other technology companies, or other experts. Free and fair elections are the heart of every democracy and we’re committed to doing everything we can to prevent misuse of Facebook at this critical time for our country.
