Social media companies say they are now more vigilant against foreign and other potential election interference after finding themselves unprepared to tackle such activity in the US presidential election two years ago.
Nathaniel Gleicher, the company's head of cybersecurity policy, wrote in a blog post that these accounts were blocked and that almost all of the Facebook pages were written in French or Russian, while the Instagram pages were written in English.
Eighty-five of the removed accounts were posting in English on Facebook's Instagram service, and 30 more were on Facebook and associated with pages in French and Russian, the post said.
The company announced its actions earlier in its investigation than typical "given that we are only one day away from important elections in the USA", he added.
Some accounts "were focused on celebrities" and others on "political debate", it added.
The company has taken steps to curtail manipulation of its platforms after being widely criticized for allowing Russian trolls spread misinformation during the 2016 election.
ABC News reports that ahead of the 2018 midterm elections, Facebook has blocked a number of accounts across both Facebook and Instagram. In August, another 652 pages also linked to Iran were taken down.
It said it would provide an update once it knew more, including whether the accounts were linked to the Russia-based Internet Research Agency, widely recognised as a "troll factory" which ran fake ads on social media during the 2016 USA election. In September, Facebook set up a "war room" in its California headquarters dedicated to rooting out disinformation related to the midterms.
Facebook, which has been blamed for doing too little to prevent misinformation efforts by Russian Federation and others in the 2016 U.S. election, now wants the world to know it is taking aggressive steps with initiatives like the war room.
