On the morning of Nov. 5, Eric Trump, one of the president’s sons, asked his Facebook followers to report cases of voter fraud with the hashtag Stop the Steal. His post was shared over 5,000 times.

By late afternoon, conservative media personalities Diamond and Silk had shared the hashtag along with a video claiming voter fraud in Pennsylvania. Their post was shared over 3,800 times.

That night, conservative activist Brandon Straka asked people to protest in Michigan under the banner #StoptheSteal. His post was shared more than 3,700 times.

Over the next week, the phrase “Stop the Steal” was used to promote dozens of rallies that spread false voter fraud claims about the U.S. presidential election.

New research from Avaaz, a global human rights group, the Elections Integrity Partnership and The New York Times shows how a small group of people — mostly right-wing personalities with outsized influence on social media — helped spread the false voter fraud narrative that led to those rallies.

That group, like the guests of a large wedding held during the pandemic, were “superspreaders” of misinformation around voter fraud, seeding falsehoods that include the claims that dead people voted, voting machines had technical glitches, and mail-in ballots were not correctly counted.

“Because of how Facebook’s algorithm functions, these superspreaders are capable of priming a discourse,” said Fadi Quran, a director at Avaaz. “There is often this assumption that misinformation or rumors just catch on. These superspreaders show that there is an intentional effort to redefine the public narrative.”

Across Facebook, there were roughly 3.5 million interactions — including likes, comments and shares — on public posts referencing “Stop the Steal” during the week of Nov. 3, according to the research. Of those, the profiles of Eric Trump, Diamond and Silk and Straka accounted for a disproportionate share — roughly 6%, or 200,000, of those interactions.

While the group’s impact was notable, it did not come close to the spread of misinformation promoted by President Donald Trump since then. Of the 20 most-engaged Facebook posts over the last week containing the word “election,” all were from Trump, according to Crowdtangle, a Facebook-owned analytics tool. All of those claims were found to be false or misleading by independent fact checkers.

The baseless election fraud claims have been used by the president and his supporters to challenge the vote in a number of states. Reports that malfunctioning voting machines, intentionally miscounted mail-in votes and other irregularities affected the vote were investigated by election officials and journalists who found no evidence of widespread voter fraud.

The voter fraud claims have continued to gather steam in recent weeks, thanks in large part to prominent accounts. A look at a four-week period starting in mid-October shows that Trump and the top 25 superspreaders of voter fraud misinformation accounted for 28.6% of the interactions people had with that content, according to an analysis by Avaaz.

“What we see these people doing is kind of like setting a fire down with fuel, it is designed to quickly create a blaze,” Quran said. “These actors have built enough power they ensure this misinformation reaches millions of Americans.”

In order to find the superspreaders, Avaaz compiled a list of 95,546 Facebook posts that included narratives about voter fraud. Those posts were liked, shared or commented on nearly 60 million times by people on Facebook.

Avaaz found that just 33 of the 95,546 posts were responsible for over 13 million of those interactions. Those 33 posts had created a narrative that would go on to shape what millions of people thought about the legitimacy of the U.S. elections.

A spokesperson for Facebook said the company had added labels to posts that misrepresented the election process and was directing people to a voting information center.

“We’re taking every opportunity to connect people to reliable information about the election and how votes are being counted,” said Kevin McAlister, a Facebook spokesperson. The company has not commented on why accounts that repeatedly share misinformation, such as Straka’s and Diamond and Silk’s, have not been penalized. Facebook has previously said that Trump, along with other elected officials, is granted a special status and is not fact-checked.

Many of the superspreader accounts had millions of interactions on their Facebook posts over the last month, and have enjoyed continued growth. The accounts were active on Twitter as well as Facebook, and increasingly spread the same misinformation on new social media sites like Parler, MeWe and Gab.

Dan Bongino, a right-wing commentator with a following of nearly 4 million people on Facebook, had over 7.7 million interactions on Facebook the week of Nov. 3. Mark Levin, a right-wing radio host, had nearly 4 million interactions, and Diamond and Silk had 2.5 million. A review of their pages by The Times shows that a majority of their posts have focused on the recent elections, and voter fraud narratives around them.

None of the superspreaders identified in this article responded to requests for comment.

One of the most prominent false claims promoted by the superspreaders was that Dominion voting software deleted votes for Trump, or somehow changed vote tallies in several swing states. Election officials have found no evidence that the machines malfunctioned, but posts about the machines have been widely shared by Trump and his supporters.

Over the last week, just seven posts from the top 25 superspreaders of the Dominion voter fraud claim accounted for 13% of the total interactions on Facebook about the claim.

Many of those same accounts were also top superspreaders of the Dominion claim, and other voter fraud theories, on Twitter. The accounts of Trump, his son Eric, Straka and Levin were all among the top 20 accounts that spread misinformation about voter fraud on Twitter, according to Ian Kennedy, a researcher at the University of Washington who works with the Elections Integrity Partnership.

Donald Trump had by far the largest influence on Twitter. A single tweet by the president accusing Dominion voting systems of deleting 2.7 million votes in his favor was shared over 185,000 times, and liked over 600,000 times.

Like the other false claims about voter fraud, Trump’s tweet included a label by Twitter that he was sharing information that was not accurate.

Twitter, like Facebook, has said that those labels help prevent false claims from being shared and direct people toward more authoritative sources of information.

Recently, BuzzFeed News reported that Facebook employees questioned whether the labels were effective. Within the company, employees have sought out their own data on how well national newspapers performed during the elections, according to one Facebook employee.

On the #StoptheSteal hashtag, they found that both The New York Times and The Washington Post were among the top 25 pages with interactions on that hashtag — mainly from readers sharing articles and using the hashtag in those posts. (People sharing the articles could have been intending to debunk the campaign.)

Combined, the two publications had approximately 44,000 interactions on Facebook under that hashtag. By comparison, Straka, the conservative activist who shared the call to action on voter fraud, got three times that number of interactions sharing material under the same hashtag on his own Facebook account.
