Despite the lessons learned from the disastrous Russian interference in the 2016 presidential election, these unnamed actors managed to use the social media platform to organize real-world events and gain hundreds of thousands of followers.
Facebook said the site "found evidence of some connections between these accounts" and those that created content to influence the 2016 presidential elections.
The company said it suspended the pages because it does not want people creating networks of accounts to mislead other users about who they are or what they're doing.
In a long series of blog posts, Facebook execs outlined how a network of posts and profiles have been working together to sow discord.

According to the DFRL, it's reasonable to conclude that some of the fake accounts were Russian in origin.
Facebook said some 290,000 users followed at least one of the pages.
While this particular investigation is still in its early stages, Facebook said it is sharing information with US law enforcement. He said it wasn't clear whether this was the "IRA with improved capabilities or a separate group" based on what the company knows so far.
Democratic congressman Adam Schiff said: "Today's announcement from Facebook demonstrates what we've long feared: that malicious foreign actors bearing the hallmarks of previously-identified Russian influence campaigns continue to abuse and weaponise social media platforms to influence the United States electorate".

A second post by Facebook's head of cybersecurity policy, Nathaniel Gleicher, said the pages and accounts had been identified "about two weeks ago" - around the same time that Gleicher was deflecting questions about fake Facebook accounts - and gave examples of the ads and posts that had been posted by the accounts.
Facebook identified influence activity around at least two issues, including a counter-protest to a "Unite the Right II" rally set next week in Washington. "These discoveries helped us uncover the other inauthentic accounts we disabled today".
