Just before the US mid-term elections, Facebook removed a total of 115 accounts it thought that ‘engaged in coordinated inauthentic behavior’.

The company said US Law enforcement contacted it on Sunday to report suspicious online activity, which they believed was possibly linked to foreign entities. Today, the social network removed 30 accounts from Facebook and 85 accounts from Instagram.
