Last year Facebook said it was going to start encouraging “high quality content” — a move that has set a lot of publishers on edge.

How does Facebook know what “high quality content” is? One way is to ask Facebook users, which the company has said it has done for a while.

Here’s a new example of a Facebook quality check in action, courtesy of CNBC social media producer Eli Langer. Thanks again, Eli! (CNBC is owned by NBCUniversal, which is an investor in this site). Langer says all of the posts Facebook showed him were from friends and people/companies he followed. (You can click on the images to enlarge them). Facebook said it has been running this survey “for several months.”

You can see the entire survey on Imgur, which may be the kind of photo-sharing site Facebook is not entirely happy about.
