The Russian influence campaign on social media in the 2016 election made an extraordinary effort to target African-Americans, used an array of tactics to try to suppress turnout among Democratic voters and unleashed a blizzard of activity on Instagram that rivaled or exceeded its posts on Facebook, according to a report produced for the Senate Intelligence Committee.
On an October afternoon before the 2016 election, a huge banner was unfurled from the Manhattan Bridge in New York City: Vladimir V. Putin against a Russian-flag background, and the unlikely word “Peacemaker” below. It was a daredevil happy birthday to the Russian president, who was turning 64. In November, shortly after Donald J. Trump eked out a victory that Moscow had worked to assist, an even bigger banner appeared, this time on the Arlington Memorial Bridge in Washington: the face of President Barack Obama and “Goodbye Murderer” in big red letters.
The Russian information attack on the election did not stop with the hacking and leaking of Democratic emails or the fire hose of stories, true, false and in between, that battered Mrs. Clinton on Russian outlets like RT and Sputnik. Far less splashy, and far more difficult to trace, was Russia’s experimentation on Facebook and Twitter, the American companies that essentially invented the tools of social media and, in this case, did not stop them from being turned into engines of deception and propaganda.
