Facebook censors user for posting a PubMed.gov article about Ivermectin: A Twitter user shared a screenshot of their Facebook censorship notice. They had simply posted an article from PubMed titled "Ivermectin Prophylaxis Used for COVID-19: A Citywide, Prospective, Observational Study of 223,128 Subjects Using Propensity Score Matching." Facebook claimed this violated one of its Community Standards, though it was unclear from the screenshot which one. The user appealed the decision but it is unclear what the outcome was.
