Twitter is making millions of dollars from just a handful of some of its most infamous users, according to a new report. New research from the Center for Countering Digital Hate (CCDH) estimates that Twitter “will generate up to $19 million a year in advertising revenue” from just 10 accounts that were once banned from the platform.

The report looked at the current engagement with 10 accounts that were previously banned for “ for “publishing hateful content and dangerous conspiracies.” The accounts were reinstated after Elon Musk’s takeover of Twitter. The group includes a number of high-profile accounts associated with extremism and conspiracy theories, including those belonging to influencer Andrew Tate, Daily Stormer founder Andrew Anglin, prominent antivaxxer Robert Malone and the Gateway Pundit.
