I just saw this post at a site that I frequent(*),:
Amazon De-ranks “Adult” Books
This is not a crisis, nor should we run screaming, but I think it is important enough that every reader, writer, publisher, editor and all champions of freedom of expression should take note. Amazon has changed its policy and has de-ranked books that it deems “adult” in nature. This includes anything they count as erotica and many non-adult LGBT books, as well. De-ranking means that they have been pulled from the sales ranks and are also not coming up in the search engine.
(and this particular euphemism always amuses me … dropping adult content rankings? That means only children are supposed to refer to Amazon ratings?)
