We’re VineSight, an AI startup that detects fake news on social networks. For over a year now, we have been analyzing the Twitter firehose, crawling the Internet’s social graph for content and connections in order to detect fake news mere moments after it’s released into the wild — regardless of whether it appears as raw text, images, memes, or video. Today, our automated technology finds fake news tweets within hours after they are posted.

This report details the most viral fake news attacks we have detected in the weeks leading up to and immediately following the Democratic Presidential debates.

Most fake news attacks start with a kernel of truth. Trolls and bots then change the story and mix in a dash of hate, outrage, and sometimes humor. Finally, they use automation to make the fake tweet go viral.

Every tweet in this report was identified by VineSight within 24 hours of its publishing, using our cutting edge AI technology and subsequently stored in our fake news database. In this report we only included tweets that passed a viral threshold of retweets and likes. Most of them have hundreds or thousands of retweets, allowing us to present a snapshot of the viral and influential fake news currently making its way through Twitter.

In this next section, we will break down the specific attacks that are being launched at the top Democratic presidential candidates. But before doing so, let’s first give you a sense of which top candidates were subjected to the most fake news in recent months. The graph below displays the percentage of fake news targeting each candidate out of the total fake news tweets detected by VineSight.

Now, let’s dive down candidate by candidate to look at the fake news attacks against each one. As you go through the tweets, draw your attention to their virality and the fact that most were published in the last few days.

Fake News Attacks on Kamala Harris

“SHE LIED: Kamala Harris Says She Was in Second Integrated Class in Berkeley — But Yearbook Pictures Prove She’s Lying”

During the debate, Kamala Harris said she was in the second integrated class in Berkeley as a child. Gateway Pundit republished a debunked old fake news story about Kamala Harris from July 2018 that claimed Harris was lying. This story was retweeted over 13,000 times on over 800 separate tweets.

“Kamala Harris IS NOT BLACK!”

After the debates, trolls and bots are questioning Kamala Harris’ “blackness” and whether she is American. To clarify, Kamala Harris’ father is Jamaican and her mother is Indian. [UPDATE: This story was recently picked up by the New York Times].

“Kamala Harris slept her way to the top”

In January 2019 the former mayor of San Francisco, Willie Brown, wrote an 137-word op-ed about Kamala Harris with the declaration, “Yes, we dated. It was more than 20 years ago.”

Since then, many fake news trolls and bots have been distorting this story and spreading fake news attacks on Kamala Harris, often using memes. The following are examples of new tweets from the past week that were retweeted thousands of times, along with a tweet our technology picked up back in January.

Fake News Attacks on Joe Biden

“Biden is pro-segregation!!!”

Joe Biden was criticized for remarks he made about his time working with segregationists while serving in the Senate in the 1970s. Fake news trolls and bots took the opportunity to generate fake news on the topic regarding Biden’s praise of late Sen. Fritz Hollings. Unlike Sens. Eastland and Talmadge who opposed integration, Hollings was a reformed segregationist and a good friend of Biden’s. Donald Trump Jr’s tweet alone was retweeted over 5300 times.
