Facebook announced on the eve of Election Day in the United States that it had blocked several Facebook and Instagram accounts since US law enforcement officials warned they could connect with foreign players.
The social media network said it found and blocked 30 Facebook accounts and 85 Instagram profiles that were said to have "coordinated non-authentic behavior".
"As part of our efforts to prevent interference in Facebook during the elections, we are in regular contact with law enforcement, external experts and other companies around the world," said Facebook security chief Nathaniel Gleicher. He said these collaborations had already helped the company to remove several "bad actors" from the site.
Facebook said that "almost everyone" Facebook's blocked accounts included French and Russian content. The company noted that the 85 deactivated Instagram accounts were mostly filled with celebrities and political news in English.
Facebook said it was still trying to figure out exactly how the accounts were, but because of the sensitive nature of the US government's warning and its close proximity to the November 6 mid-term elections, it chose to take precautionary measures.
Facebook has received huge criticism of its failure to cope with the Russian influence campaigns that helped pollute online online during the 2016 presidential election. The US intelligence agency has concluded that Russia's efforts were aimed at promoting the election in favor of Donald Trump.
Facebook has publicly stated that it is determined to ensure the authenticity of each user on its site, indicating how it blocks 82 Facebook accounts linked to Iran on October 26 after the US authorities have notified them of "non-original" pages they distribute divisive political positions to about a million fans.
