Hate Speech’s Rise on Twitter Is Unprecedented, Researchers Find

Before Elon Musk bought Twitter, slurs against Black Americans showed up on the social media service an average of 1,282 times a day. After the billionaire became Twitter’s owner, they jumped to 3,876 times a day.

Slurs against gay men appeared on Twitter 2,506 times a day on average before Mr. Musk took over. Afterward, their use rose to 3,964 times a day.

And antisemitic posts referring to Jews or Judaism soared more than 61 percent in the two weeks after Mr. Musk acquired the site.

These findings — from the Center for Countering Digital Hate, the Anti-Defamation League and other groups that study online platforms — provide the most comprehensive picture to date of how conversations on Twitter have changed since Mr. Musk completed his $44 billion deal for the company in late October. While the numbers are relatively small, researchers said the increases were atypically high.
