Bot Sentinel

Bot Sentinel is a Twitter analytics service founded in 2018 by Christopher Bouzy. It tracks disinformation, inauthentic behavior and targeted harassment on Twitter.

History
Bot Sentinel was founded in 2018 by American tech entrepreneur Christopher Bouzy. Its stated goal is to improve Twitter users' experience, and it says that people should be able to engage in "healthy online discourse without inauthentic accounts, toxic trolls, foreign countries, and organized groups manipulating the conversation." Bouzy was inspired to create Bot Sentinel by the Russian interference in the 2016 United States elections.

In August 2022, Twitter said it would revoke Bot Sentinel's access to its APIs, saying that Bot Sentinel's tracker activity was in violation of its API policies. At the time, Twitter was in a legal dispute with Elon Musk over his acquisition of the platform.

Bot Sentinel's scoring system for identifying problematic accounts is used in the social media platform Spoutible, which was also created by Bouzy. Spoutible was launched in February 2023.

Investigations
Prior to the 2020 United States presidential election, Bouzy said that inauthentic Twitter accounts were promoting false or unverified claims of voter fraud, or advancing then-President Donald Trump's unfounded claims of impropriety in the counting of ballots.

In October 2021, Bot Sentinel released their analysis of more than 114,000 tweets about Prince Harry and Meghan, the Duke and Duchess of Sussex, as a result of which they found 83 accounts with a combined number of 187,631 followers that were possibly responsible for approximately 70 percent of the negative content posted about the couple. The report prompted an investigation by Twitter. The company stated that it found no evidence of "widespread coordination" between the accounts, and said that it had taken action against users who violated Twitter's conduct policy. Bouzy was himself responsible for initiating a discourse on Twitter that criticized Harry's brother and sister-in-law Prince William and Catherine, the Prince and Princess of Wales, for their appearance by tweeting that they were "aging in Banana years".

A January 2022 Bot Sentinel report said that online hate campaigns targeting Harry and Meghan had become a "cottage industry" for a few online influencers exclusively posting about the couple. The report described it as "a lucrative hate-for-profit enterprise" where "racism and YouTube ad revenue are the primary motivators", and described the conspiracy theories the influencers promoted about Harry and Meghan as being reminiscent of the QAnon conspiracy theory.

Bouzy has also conducted paid-for private research for the legal team of Amber Heard as well as unpaid research on bot attacks against public figures such as Heard, Meghan Markle, Pete Buttigieg and Lisa Page.

Operation
Bot Sentinel relies on machine learning to identify Twitter bots, using millions of tweets from suspended accounts that are categorized as being either bots or not bots. The service is trained to identify what Bouzy calls "problematic accounts". Its algorithm gives Twitter accounts a score between 0% and 100%, which is based on their resemblance to accounts that violate Twitter's rules.

As of October 2022, Bot Sentinel consisted of Bouzy and three programmers and data scientists. Bot Sentinel receives funding through donations on its website, which allows its browser extensions and hate trackers to be used free of charge by the general public. Bot Sentinel is hosted by Ionos.
