I had the impression Goodreads was a link-farming book/warez site. Is it something real or apparent competing-with-the-Jones', Chef de Claque toxic positivity, whether human or bot?
If you’re just looking at the top reviews for a book it’s more questionable; they tend toward the extremes: enraptured encomiums about how beautiful and important and bold the book is, or insult-laden rants where the book is a whipping post for the reviewer to show off what a biting sense of humor they have.
