Shortly after taking over the company last October, Musk said he would expand a preexisting paid version of Twitter to include paying for a blue check mark.

The study, which used machine-learning tools to identify likely antisemitic tweets, found that the average weekly number of such posts “more than doubled after Musk’s acquisition.”

Twitter has privately demanded that the suspended journalists delete the tweets that drew Musk’s ire in the first place – a condition the reporters have refused to accept.

More than half of 17.5 million users who responded to a Twitter poll created by Musk over whether he should step down as head of the company had voted yes by the time the poll closed Monday morning.
