I can always tell when another person has hung out a shingle and announced that they will only charge you x amount to contact the top whatever number Amazon reviewers in your genre. Suddenly, I start getting hammered with over 100 review requests a day ---many of which are duplicated and sent again and again. Almost always it is a book that if the person had bothered to read my blog they would know it isn't something I would have read and reviewed.
Thanks to a recent post on the The Passive Voice here I saw a piece at The Writer Shack on what to do and not do regarding review requests. I agree with much of the post that can be found here.
Just a reminder, I remain closed to nearly everything except those books that fit my Senior News newspaper column and authors I have reviewed before.
