@DrEvanGowan @eartharxiv They do, but it's too weak, and too retrospective. I reported a paper last year which was then withdrawn - I've forward the email I sent on to you... I think it is worth reporting stuff which falls under "Commentaries and opinion pieces (i.e. an article that predominantly reflects the author’s opinion or beliefs on a given subject, typically framed in a provocative or controversial manner)..." (@EarthArXiV claims not to accept such stuff...).
