From the email forwards your crazy uncle used to send you to facebook shares, horseshit masquerading as fact has long been a problem. Snopes (imperfect and in the old days they seemed to have a bit of a thumb on the scales in favor of conservative horseshit, but reasonably good) has been around a long time for this reason.
But big media outlets believe they are not the primary transmitters of horseshit, even when they are, and are thrilled at the thought that they can monopolize the linkbait and shut out smaller independent sites.
If anyone cared about this little blue lemonade stand, I'm sure it'd be on a "fake news" list. I don't use facebook (or anything else really) to promote it, but if I did I'd probably get annoyed.
