Facebook has updated an old blog post from 2017, which announced that it would reduce News Feed links to scammy sites, probably since this update could be considered an expansion of that.

The social network's addendum reads:

"Starting today, we're rolling out an update so people see fewer posts that link out to low-quality sites that predominantly copy and republish content from other sites without providing unique value. We are adjusting our Publisher Guidelines accordingly."

It has also confirmed the change to TechCrunch, telling the publication that it will identify scrapers by comparing their text with other websites. If a website also uses clickbait headlines or have landing pages filled with low-quality ads, then the social network will automatically demote links to it in the News Feed. By doing so, Facebook is likely hoping that they'll get less traffic from the platform, thereby discouraging others from doing the same thing.
