From The Telegraph: Author backlash over Amazon’s new online review crackdown by Andrew Hough
Scores of authors in Britain and across the Atlantic have recently reported that their reviews have either mysteriously disappeared or were never published.
Amazon has now admitted that it has introduced a ban on authors leaving reviews about other people’s books in the same genre because they may pose a “conflict of interest” and cannot be impartial about their rivals.
This means that thriller writers are prevented from commenting on works by other authors who write similar books.
Critics suggest this system is flawed because many authors are impartial and are experts on novels.
In recent weeks, some authors said they had more than 50 reviews deleted without notice, provoking waves of critical comments and posts on blogs and internet forums.
