RUSSIAN MEDDLING ON SOCIAL MEDIA MORE COMMON THAN THOUGHT, REPORT SAYS.

WASHINGTON • Russia’s sweeping political disinformation campaign on U.S. 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 U.S. citizens, and encourage them to vote for Trump.”

The report from New Knowledge says there are still some live accounts tied to the original Internet Research Agency, which was named in an indictment from special counsel Robert Mueller in February for an expansive social media campaign intended to influence the 2016 presidential election. Some of the accounts have a presence on smaller platforms as the major companies have tried to clean up after the Russian activity was discovered.

“With at least some of the Russian government’s goals achieved in the face of little diplomatic or other pushback, it appears likely that the United States will continue to face Russian interference for the foreseeable future,” the researchers wrote.

The New Knowledge report says that none of the social media companies turned over complete data sets to Congress and some of them “may have misrepresented or evaded” in testimony about the interference by either intentionally or unintentionally downplaying the scope of the problem.
