1/2 System as a whole (ie, academia) worked, but more narrow Econ ref process didn’t. Unfortunately, seems very hard to pick up, aside from the unrealistic (in retrospect) amount of work for a 2nd yr PhD.
How did the system work? It was an R&R at the QJE (allegedly) so the economist reviewers clearly had no idea.

Pornhub's removal of all non-verified content led to a 41% drop in traffic within 1 month.
Much of the displaced traffic was absorbed by competing platforms, including less regulated fringe websites (+55% visits) and mainstream competitors (+10%).
