To try and mitigate public perception about its Russian advertising scandal, Facebook appears to have bought advertisements from other platforms also embroiled in the same mess.

In September, The Washington Post broke the story that a Russian "troll farm" connected to the Kremlin purchased $100,000 in Facebook advertisements designed to heighten social tensions and sow political unrest during the 2016 US presidential election (the ads have yet to be made public). Predictably, the social network had a shit storm on its hands.
