If you haven't noticed, Amazon is getting itself into a pretty serious PR fiasco. Web 2.0 is in a tizzy. For a little more background, have a look at Dear Author's excellent explanation. The wonder of hyperlinking: I don't have to explain this full issue because lots of people have done it better than I have.
As a librarian, I have issues with censorship. And to me, what Amazon is doing is tantamount to censorship. So I'm joining the Smart Bitches in their effort to sabotage the term amazon rank.
My policy, and our library's policy, and the sane thing to do, is to let parents decide what "adult content" is -- this means parents have to be aware of what their kids are surfing. And then buying online. Hard work, being a parent. You have kids, you have responsibilities. Don't expect the world to police itself because the world won't always agree with you on what is appropriate.
Censorship is worse than pretty much anything. To me, it doesn't matter what is being censored. It prevents people from becoming informed and making their own decisions. It eliminates choice. It is an insidious attack on freedom of thought and freedom of expression in the name of "decency." Censorship makes me sick.
Now, I know Amazon isn't a library. Amazon is a company. Amazon can do whatever the hell they like with their rankings, and as long as consumers keep supporting them they'll continue to do whatever they like. Either someone has made a really stupid decision, or Amazon thinks this is what their consumers want. But I won't be buying anything from them until they stop being evil (which, being an optimist, I'm sure they will shortly because I'm sure it was some stupid automated oversight), and I intend to politely suggest that everyone I know does the same.
