I've published 20 bestselling books in the last ten years and during that time I've seen so many scams come and go. Scams involving fake reviews, Goodreads reviews, fake kindle purchases, social media followers and more. Over the years I've watched authors who participate in these scams come and go. They never last. Don't be tempted, you'll feel a lot better about your success if you find it naturally. Plus there's a lot of bad energy around this kind of thing. It does you no good in the long run. Thank you Medium for trying to combat this.
