> I also think that if comments were enabled on arxiv preprints, this could have led to a much more rapid conclusion to the fraud. Probably a materials scientist who read the paper realized this was fraudulent but wasn’t able to get that view quickly to the economists who were actually reading and discussing the paper. A well-written arxiv comment explaining why the data on materials similarity, for example, couldn’t be true, would have gone a long way.

could this work outside/on top of arxiv?
