The Verge (one of Vox’s publications) has a detailed story on how Facebook is dealing with “clickbait” in its news feeds, here. Clickbait comprises a headline that you must click on to find out what the story is really about.
Publishers who create deliberately misleading or “leading on” headlines (especially for marketing purposes) could find themselves pretty much cut out of trending topics and news feeds, the story says, But it would probably affect only the worst offenders.
I get very annoyed at videos that keep nagging on with endless sales pitches, particularly on financial products. Some of Porter Stansberry’s video material (on the supposed reserve currency crunch) and some videos on “conservative” websites seem to do this.
