Major technology companies and social media platforms have removed, suppressed or flagged the accounts of over 800 prominent individuals and organizations, including medical doctors, for COVID-19 misinformation, according to a new study from the Media Research Center (MRC).

MRC’s Free Speech America CensorTrack, an initiative that monitors acts of censorship across online platforms, identified over 41 instances between March 2020 and February 2022 in which doctors, scientists and medical organizations were censored, according to the results of a study shared with Daily Caller News Foundation.

The study focused on acts of censorship on major social media platforms and online services, including Facebook, YouTube, Instagram, Twitter, LinkedIn, Google Ads and TikTok.
