All the books have approximately the same number of reviews. Is Amazon completely uninterested in dealing with fake reviews?
The amount of profit Amazon will make from “Tom Lesley” and the like is negligible compared to the actual long term reputational damage that low quality products do to their brand.
What would however be a big problem for Amazon is the marketplace becoming unusable and untrustworthy in the eye of users.
Seems like "Lesley" should get himself a Midjourney account to go along with thhe ChatGPT account, because his covers kinda suck.
