Facebook is fed up with clickbait headlines and the websites that mock them. The Onion and its sister site, Clickhole, have become so good at mimicking those headlines that Facebook is now testing a Satire tag to help users tell the difference. It Did For These People, and another like It’s Time To Admit That Depression Is Real, Except For Teens Who Are Just Being Moody. The tag would appear as [Satire] in front of the fake headlines. We are running a small test which shows the text [Satire] in front of links to satirical articles in the related articles unit in News Feed.
