“Historically, we have relied on our community to help us understand what is fake and what is not. Anyone on Facebook can report any link as false, and we use signals from those reports along with a number of others – like people sharing links to myth-busting sites such as Snopes – to understand which stories we can confidently classify as misinformation. Similar to clickbait, spam and scams, we penalize this content in News Feed so it’s much less likely to spread,” he wrote.
