As an author I can’t condone this sort of thing. Either a reader likes reading my books, and buys another one, and hopefully leaves a review, good or bad, or they don’t. I’ll always be poor because I’m honest and trying to make my living as an author on the strength of my writing talent and marketing skills alone. I have a readership and I love each and every one of them. That’s enough for me. Bread and water ? I’ll eat and drink that rather than make thousands unethically 🙂
