Circa 2009 I was hired to build a Facebook graph app that did just this, only for dating profiles. Thankfully it was acquired and buried by the shady sociopaths who hired me to build it, before it ever saw the light of day.

However, there were many, many apps that also did the same. A number of dating apps, companies like Zynga, business networks like BranchOut etc. They were just inhaling data wholesale, especially Likes which were fully exposed to all friends in your graph.

I could totally see how you could use that data circa 2014 to build psych profiles and resell it for sophisticated targeting years later.

There is an enormous risk of companies who rose and fell during the Zynga era to have resold or improperly disposed of FB profile data during their final liquidation. This is just the tip of the iceberg.
