"Thousands of Russian trolls targeted national events during the 2016 U.S. presidential election to infiltrate the online conversations of millions of Americans, according to a new analysis of a database of recovered troll tweets by NBC News.
The records show how digital communications tools invented by U.S. companies, such as Twitter and Facebook, were instead exploited by the Kremlin-backed agents to promote autocracy and fear.
The recovered data, using the list of Russian troll accounts identified by Twitter and released by Congress, shows that the online actors were adroit at bending those tools of transparent communication to their malign purposes.
NBC News compiled 202,973 tweets from 454 of the 2,752 accounts into its database, making it "one of the largest" known to date, according to Jonathan Albright, research director at Columbia University's Tow Center for Digital Journalism.
Those tweets earned 2.1 million retweets and nearly 1.9 million favorites.
"Thinking about this in a binary of 'did it cause someone to change their vote?' is overly narrow," said Laura Rosenberger, director of the Alliance for Securing Democracy. "It's about influence over time."
NBC News compiled its database by cross-referencing the list of identified accounts against data held by three sources familiar with Twitter's API, an online system that allows software developers to work with the data underlying users' tweets. The sources asked that their names be withheld to avoid being identified as possibly violating Twitter's developer policy.
According to the dataset, Russian twitter troll volume increased significantly on July 21, two days after Trump became the official Republican nominee, and continued at the same intensity or higher for the rest of the year.
Throughout 2016, the trolls' tweets and retweets spiked during key campaign events.
The first big spike for the trolls was March 22, 2016, when three suicide bombers killed 32 in Brussels.
Daily troll volume suddenly increased several-fold. They linked the terrorist act claimed by ISIS with a perceived threat posed by Muslim refugees to the U.S.
JeanneMccarthy0: "#IslamKills this is seriously getting out hand! I'm so scared for the future of my children! #PrayForBrussels #StopIslam"
RyanMaxwell_1: "#Brussels Let's close all mosques! #freespeech is overrated! #IslamKills"
Ben Nimmo, a senior fellow at the Atlantic Council, a think tank, told NBC News in an email that the surge of tweets sought to "demonize Muslims, migrants, refugees and anyone who supports them, and to panic real Americans into increasingly extreme views."
But the trolls were just getting warmed up.
Americans may have thought they were using hashtags during the election to discuss politics with each other. They didn't know they were also talking to Russians thousands of miles away in a troll factory.
The top hashtags were the generic #politics, followed by #maga, #Trump, #news, and #NeverHillary.
"Some of the trolls participated in trending hashtags by inserting entirely appropriate content, perhaps as a way of getting their screen names in front of other people and gain a following," said David Allen, an analyst at software company Neo4j who assisted NBC News with analyzing the database.
"Others would try to 'hijack' a hashtag," inserting disruptive content into a trending topic, "or draw a non-political hashtag into a discussion of politics," he said.
Troll activity spiked again during the final presidential debate, rehashing conspiracy theories and retweeting divisive content. The trolls alternately said the debate was rigged, or a total win for Trump.
But the trolls did speak in a chorus when it came to one hashtag.
About 9 a.m. on Oct. 19, 2016, the morning of the final debate, the Russian troll account "WorldOfHashtags" kicked off a new online conversation.
"The last presidential #debate starts soon. So let's discuss #RejectedDebateTopics," the troll wrote. Moments earlier they had referred to it as a "hashtag game" that was "hosted" by "GiselleEvns," another of the Russian troll accounts.
Immediately a cluster of the trolls started pumping out tweets with the hashtag, several tweets per minute.
Later that day over 600 Twitter users, who were not on the list of trolls and may have included authentic Americans, added hundreds of their own twists to #RejectedDebateTopics, like "Which diagnosis fits Donald, sociopath or narcissistic personality disorder," "Good places to hide emails" and "Knock knock... who's there? Interrupting cow."
Twitter didn't respond to NBC News requests to confirm whether the hashtag had "trended" for other users and appeared in a box that would have promoted it to new users.
When it came to tweets sent in real-time during the debate, popular Tennessee Republican party impostor account @TEN_GOP took charge, sending the majority of the original tweets.
TEN_GOP: "Iran payment wasn't just ransom, it was money laundering. The deal was set up by Hillary when she was sec of state #debate #debatenight"
TEN_GOP: "Donald Trump's ending was perfect! RT if you are also sure that #Trumpwon! #Debate"
Those tweets got thousands of retweets, likes and user comments.The account also directly tweeted compliments to Trump during the debates.
"@realDonaldTrump Can't wait to see you in the WH," tweeted the Russian troll an hour before the debate began. Right as the debated ended, the Russian troll account tweeted to Donald Trump, "We are proud of you!"......"
