Amazon Fail: Update

Thanks to Salon for pointing us to Dear Jane who's unraveled a little bit of this mystery:

"At the suggestion of someone I looked up the category meta data provided by the publisher to Amazon. I looked up over 40 books that had been deranked and filtered out of search engines. It appears that all the content that was filtered out had either 'gay', 'lesbian', 'transgender', 'erotic' or 'sex' metadata categories. Playboy Centerfold books were categorized as 'nude' and 'erotic photography', both categories that apparently weren’t included in the filter. According to one source, the category metadata is filled in part by the publisher and in part by Amazon.

The question is then who implemented the policy of marking GLBT books as adult and who knew of the implementation? What kind of supervisory person signed off on it?"
