This is an embarrassing and ham-fisted cataloging error for a company that prides itself on offering complete selection.Apparently they use 'adult' to mean porn, which presumably means that AE as erotica will be re-ranked at some point. Which is nice for me, although I could have a discussion separately on what exactly erotica vs. porn actually is. And why they can't just do an opt-in option for 'adult' material, the way Google does.
It has been misreported that the issue was limited to Gay & Lesbian themed titles in fact, it impacted 57,310 books in a number of broad categories such as Health, Mind & Body, Reproductive & Sexual Medicine, and Erotica. This problem impacted books not just in the United States but globally. It affected not just sales rank but also had the effect of removing the books from Amazon's main product search.
Many books have now been fixed and we're in the process of fixing the remainder as quickly as possible, and we intend to implement new measures to make this kind of accident less likely to occur in the future.
Battle for another day, especially since I suddenly started feeling like crap. Is there such a thing as finishing-your-book-sickness? Because I'm crashing hard.
