On Monday night, economist Patrick Chovanec surveyed the wreckage of Elon Musk’s Twitter with exasperation. “This place has become a hive of anti-vaxx paranoia,” he sighed. “I think I’m doing some good by rebutting it, but I’m just pissing into the wind. It’s depressing.”

He’s not alone. “I feel like anti-vaxxers on Twitter have gotten noticeably more insane since Elon took over,” said reporter Alex Griswold. “Which isn’t even a critique really… there is something to the sunlight-as-disinfectant idea. It might’ve been better if these folks were more obviously bonkers two years ago.”

How insane have they gotten?
