Yesterday YouTube announced it’s purging videos and accounts that spread misinformation about Covid-19 vaccines. In the blog post sharing the policy, YouTube said it will remove content that “falsely alleges that approved vaccines are dangerous and cause chronic health effects, claims that vaccines do not reduce transmission or contraction of disease, or contains misinformation on the substances contained in vaccines.” For years, YouTube executives have faced criticism for allowing conspiracy theorists and radical hatemongers to thrive on its site. The decision to remove anti-vaccine content is its strictest policy yet toward misleading, conspiratorial content. In the last year, YouTube has removed more than 130,000 videos that violated its existing Covid-19 misinformation policies.
