There has been an explosion in "the onion"-like fake news sources that say they're satire somewhere on the site, yet by reading the article without that context one would have no way of knowing unless they fact-check. The articles have very little, if any, of the kind of humor that defines satire. They usually publish fictional pro-GOP headlines that are often shared on social media with strong reactions from uninformed commenters. Not flagging these articles with an appropriate label pretty much ensures that this whole facebook-based fact checking feature is nothing more than a vaporware PR campaign.
