Authors should support booksellers that support them in return. Don’t chase sites that seem to despise your very existence. Vendors that “troll” the review process to disallow both peer reviews (author-to-author) and established reviewer groups should be avoided. Instead, authors should focus marketing efforts on author-friendly sites, such as Barnes & Noble and Smashwords. Both offer easy ways to “gift” books to reviewers, and then will allow reviews to be posted without behind-the-scenes skullduggery. They also tend to pay higher royalties per unit sold on most types of editions.
