Jane, here is the conclusion and suggestion on how to fix the problem.
“So how to fix it? It starts with people: Goodreads desperately needs more human moderation to monitor the goings-on. Obviously, part of any healthy discussion is the ability to express displeasure — those one-star reviews, ideally accompanied by well-argued rationales, are sacrosanct — but Goodreads has enabled the weaponization of displeasure.
It’s not just fledgling authors being pummeled. Earlier this year, Elizabeth Gilbert, the best-selling author of “Eat, Pray, Love,” decided to withdraw a forthcoming novel, “The Snow Forest,” after Goodreads users bombarded its page with one-star reviews objecting primarily to the fact that the novel (which no one had yet read) was set in Russia and would be published at a time when Russia and Ukraine were at war. There is most likely no way to eliminate personal attacks entirely from the site — or from the internet, for that matter — but having more human beings on hand to mitigate the damage would certainly improve the experience.”
