@Lennvor In the article its more like someone asked to do peer review for a proposal. Depending on your familiarity with the topic, that can take half a day or so… but someone noted with ChatGPT, they could get it done quick (my estimate, half an HOUR).
Peer review for proposals is generally compensated, but peer review of research papers is NOT (its community service, you review me, I review you for free so the publisher can cash in our labor).
There is thus an incentive to expedite reviews.
