I got this in my email:
Paying for a review is extremely stupid and nobody should do it unless, perhaps, it’s a Kirkus review, but Ghanghata here isn’t Kirkus. Ghanghata is disgusting by soliciting filthy lucre for a book review. Do not pay Ghanghata. Do not communicate with the Ghanghatas of the world. Once Ghanghata slime gets on you, it never washes off. You will always be the writer who paid a Ghanghata to write nice things about your book.
Just say no to Ghanghata.
