Mark Zuckerberg has said that fighting coronavirus misinformation is one of his “top priorities,” yet Facebook’s ad policies have been slow to catch up. Now, the company will no longer allow advertisers to target users based on their interest in “pseudoscience,” according to The Markup.

The publication discovered the category after seeing an ad for an “anti-EMF beanie,” apparently meant to “protect” against radiation from smartphones. Facebook later told The Markup it removed the category from its ad platform.
