Frustrated With Amazon

My cover for THE WIZARD MURDERS was disallowed from advertising on Amazon because of "blood splatter?" Are you kidding me? Have they viewed the cover of almost every single "Dexter" book? Does Amazon plan to take down virtually all of the "Dexter" books, several Stephen King novels, Dracula....I could go on. They'll let me SELL the book (since 2012), but not ADVERTISE it? Doesn't that seem silly?
