Journalists often concoct an "ongoing" narrative to make it sound like there is a big trend when there are only one or two anecdotes. Write a weak article with one example, follow it up with a second article with a second example, then write a third article proclaiming that something is "sweeping the nation," linking to what "we previously reported."

The linked title could just as well have said "when you're staying in a stranger's home," but that doesn't carry as much currency as "AirBnB." I think that's clickbait, albeit subtle.
