Doubts Cast Over Elon Musk’s Twitter Bot Claims

Filings made by Elon Musk’s legal team in his battle with Twitter have been questioned by leading bot researchers.

Botometer – an online tool that tracks spam and fake accounts – was used by Mr Musk in a countersuit against Twitter.

Using the tool, Mr Musk’s team estimated that 33% of “visible accounts” on the social media platform were “false or spam accounts”.

However, Botometer creator and maintainer, Kaicheng Yang, said the figure “doesn’t mean anything”.
Mr Yang questioned the methodology used by Mr Musk’s team, and told the BBC they had not approached him before using the tool.

Mr Musk is currently in dispute with Twitter, after trying to pull out of a deal to purchase the company for $44bn (£36.6bn).

A court case is due in October in Delaware, where a judge will rule on whether Mr Musk will have to buy it.
In July, Mr Musk said he no longer wished to purchase the company, as he could not verify how many humans were on the platform.

Since then, the world’s richest person has claimed repeatedly that fake and spam accounts could be many times higher than stated by Twitter.

In his countersuit, made public on 5 August, he claimed a third of visible Twitter accounts, assessed by his team, were fake. Using that figure the team estimated that a minimum of 10% of daily active users are bots.

Twitter says it estimates that fewer than 5% of its daily active users are bot accounts.

Correct threshold

Botometer is a tool that uses several indicators, like when and how often an account tweets and the content of the posts, to create a bot “score” out of five.

A score of zero indicates a Twitter account is unlikely to be a bot, and a five suggests that it is unlikely to be a human.
However, researchers say the tool does not give a definitive answer as to whether or not an account is a bot.

“In order to estimate the prevalence [of bots] you need to choose a threshold to cut the score,” says Mr Yang.

“If you change the threshold from a three to a two then you will get more bots and less human. So how to choose this threshold is key to the answer of how many bots there are on the platform.”

Mr Yang says Mr Musk’s countersuit does not explain what threshold it used to reach its 33% number.

“It [the countersuit] doesn’t make the details clear, so he [Mr Musk] has the freedom to do whatever he wants. So the number to me, it doesn’t mean anything,” he said.
