An investigation by The Markup has revealed that Facebook has been allowing advertisers to run adverts targeting people interested in 'pseudoscience'.

Mark Zuckerberg had previously stated that 'one of [his] top priorities is making sure that [Facebook users] see accurate and authoritative information across all of [Facebook's] apps'.

Facebook subsequently removed the pseudoscience interest category. The category contained more than 78 million people, according to Facebook’s ad portal.
