Last week we reported that Amazon had removed several yaoi manga from the Kindle Store on the grounds that it did not meet their content guidelines. I spoke to Fred Lui of Digital Manga Publishing, the publisher of the deleted manga, and he said that Amazon didn't give any more specific reason than that, although he did note that there seemed to be a new guy who was being "overzealous."
The Kindle Store still offers plenty of yaoi manga, including some fairly steamy titles, so Amazon doesn't seem to be deleting all the yaoi by any means. However, Animate U.S.A., a Japanese publisher that publishes yaoi manga exclusively on the Kindle, reports that Amazon has removed some of their books as well. I e-mailed them last week to ask about this, and this is the reply I got:
As you may know, some titles are already removed by Amazon without any specific reasons.
We just know that the titles contain content that is in violation of their content guidelines.
The e-mail did not include specifics, but I looked through their press releases and came up with three titles that Animate announced but that are not currently available in the Kindle Store: vol. 1 of Mister Mistress (vol. 2 is still available, and both can be bought used in print through Amazon), Delivery Cupid, and Pet in Love, a Pet on Duty side story (Pet on Duty is still available). I have e-mailed Animate to confirm that these titles were removed by Amazon and not by the publisher.
While the deleted Digital titles are still available via the Nook and Digital's own eManga website, Animate U.S.A. publishes only to the Kindle, so these titles are no longer available digitally.
A side note: In the earlier post, we mentioned several non-yaoi graphic novels that seemed to be at about the same level of explicitness as the ones deleted; one of these, Christmas Creampie, is no longer available in the Kindle Store.
