Goodreads is like Yelp for books.

Find a book written by a right wing author. Hundreds of ratings, and the reviews don't even talk about the book beyond the description. Lots of pesudo-science and bad faith arguments.

I got scammed by a few books. And worse, call out the issues with the books and your review gets shadow banned. Amazon doesn't have a urgency to remove these fake reviews because it'll affect sales.
