Cait Corrain is an author who had a highly anticipated book called Crown of Starlight coming out in May of 2024. But now her book has been shelved after she admitted to using Good Reads to review bomb a bunch of other writers’ forthcoming books. Most of her targets were Black or queer, while Corrain is white. This story has a LOT of twists and turns, including her inventing an obviously fake conversation with an obviously fake person.
Canadian author Xiran Jay Zhao was the first person I saw to bring it to wider attention online. They first noticed that Cait’s book Crown of Starlight was getting good reviews from the same accounts who were trashing other books, some of which were not even out yet. 
Xiran Jay Zhao also created a 31-page Google document of screenshots showing a bunch of the alleged-but-now-admitted fake GoodReads accounts, screenshots of conversations, and other damning receipts. https://docs.google.com/document/d/1__mO1uqIqcmupBAPKwXDzlUbZIwtY6fKf0S1Y0SNz0E/edit See omnystudio.com/listener for privacy information.
