Facebook, YouTube and Twitter all banned harmful covid-related misinformation as the pandemic took hold throughout the world. But the false claims are still proliferating.
On YouTube, the accounts of six out of 12 anti-vaccine activists identified by the Center for Countering Digital Hate as being responsible for creating more than half the anti-vaccine content shared on social media are easily searchable and still posting videos. On Facebook, researchers at the left-leaning advocacy group Avaaz ran an experiment in June in an effort to show how anti-vaccine material gets pushed to people. Two new accounts it set up were recommended 109 pages containing anti-vaccine information in just two days.
