"Social media platforms have generally abrogated responsibility for the dissemination of misinformation," said Dr. William Pelfrey Jr., professor in the Wilder School of Government and Public Affairs at Virginia Commonwealth University."While Twitter and some social media sites restricted Covid-19 misinformation, rolling back those limitations serves only one master – profit," Pelfrey suggested."Those who are intent on spreading lies will do so somewhere, as evinced by the dramatic rise in users on non-mainstream platforms.Social media platforms continue to struggle with finding a way to balance legitimate free speech with the preservation of public health."The research findings are very clear that misinformation can contribute to Covid-19 morbidity and mortality as well as perpetuate stigma, xenophobia, and hate speech," said Stolow."
