On the eve of mid-term election, Facebook said Monday that it had blocked 115 social media accounts after receiving a warning from federal law enforcement officials of "coordinated inauthentic behavior" that could be linked to foreign entities.
In a blog post Monday night, Nathaniel Gleicher, Facebook's head of cyber security policy, said 85 of the accounts were on the company's Instagram service, with the remainder on Facebook itself.
Gleicher wrote that the accounts were immediately blocked after the company was notified Sunday evening of suspicious behavior and that the questionable accounts — potentially linked to foreign entities — are being investigated "in more detail."
