I'm so sorry this has escalated for you. The reason I'm staying anonymous in my own version of this - an aggressive, completely unfair 1* review I've just received on one of my ebooks. If I openly challenged this guy he sounds like the nasty sort of character who'd up his campaign and start leaving his poison on all my other books. Amazon has got to pay more attention to the content and the systems of these people. 'Read All My Reviews' reveals he'd given similar quick put-downs (all written ON THE SAME DAY) to several other books in the same genre. The only other reviews were 2 5 star raves for his own books! It's the kind of  spamming of the competition that TripAdvisor has taken action on. Amazon has to do the same.
