Any "Ranking of X" or "Curated List of Y" becomes useless and untrustworthy as soon as a cottage industry springs up around it where people can pay to boost their ranking or get on the lists.

This seems like The Big Problem that recommendation / discovery sites have been failing to solve for decades.
