Facebook Inc. added warnings to 40 million pieces of misinformation about the coronavirus on its main social network in March, part of an effort to stem the spread of bad advice and misleading articles.
Hundreds of thousands of posts Facebook deemed harmful were removed entirely, according to a blog post on Thursday by Guy Rosen, the company’s vice president for integrity. In the next few weeks, users who liked, commented or reacted to misleading posts that were later taken down will be shown messages in their news feeds linking to factual information about Covid-19, the company said.
