It’s no surprise that people pushing anti-mask arguments popped up online around the time the coronavirus pandemic hit the United States in March and April.
But here is what might surprise you: The audience for misleading anti-mask posts on Facebook has grown sharply in the last eight weeks, despite the growing evidence that masks can help prevent the spread of the virus.
The number of people who have joined anti-mask Facebook groups has grown 1,800 percent, to more than 43,000 users, since the beginning of August, according to an analysis of data provided by Crowdtangle, a media tool that Facebook owns. Almost half of the 29 antimask groups discovered by The New York Times were created in the last three months, with names like “Mask off Michigan” and “Mask Free America Coalition.”
