Report: Russia still using social media to roil US politics

Russia's sweeping political disinformation campaign on US social media was more far-reaching than originally thought, with troll farms working to discourage black voters and "blur the lines between reality and fiction" to help elect Donald Trump in 2016, according to reports released Monday by the Senate intelligence committee.

And the campaign didn't end with Trump's ascent to the White House. Troll farms are still working to stoke racial and political passions in America at a time of high political discord.

The two studies are the most comprehensive picture yet of the Russian interference campaigns on American social media. They add to the portrait investigators have been building since 2017 on Russia's influence though Trump has equivocated on whether the interference actually happened.

Facebook, Google and Twitter declined to comment on the specifics of the reports.

The reports were compiled by the cybersecurity firm New Knowledge and by the Computational Propaganda Research Project, a study by researchers at the University of Oxford and Graphika, a social media analysis firm.

The Oxford report details how Russians broke down their messages to different groups, including discouraging black voters from going to the polls and stoking anger on the right.

"These campaigns pushed a message that the best way to advance the cause of the African-American community was to boycott the election and focus on other issues instead," the researchers wrote.

At the same time, "Messaging to conservative and right-wing voters sought to do three things: repeat patriotic and anti-immigrant slogans; elicit outrage with posts about liberal appeasement of 'others' at the expense of US citizens, and encourage them to vote for Trump."
