Reviews are around 90-95% AI, all the exact same length, and all written in the same style. Customers notice them immediately - don't do it, it will tank your sales. Sometimes reviews will copy and paste already existing reviews so you'll have two to three of the exact same reviews on your book. They say they reject reviews that don't meet their guidelines but in reality almost all are automatically approved - AI or otherwise. I requested take downs of the copy and pasted reviews but always refuse saying it breaches Amazon's guidelines (it doesn't, the fraudulent reviews do). Also, the vast majority of the books you have to review to get books are written mostly by AI. AI Books, AI reviews, lots of money for Kevin. If you care about your book, avoid at all costs. The reviews will stay up permanently on Amazon.
