This hacker employed an interesting technique to get many gay and lesbian books banned on Amazon.
It is a technique that could also be used to cause problems for any set of books or
ideas that you don't like. I discovered it following the Twitter hash tag '#amazonfail".

I don't condone what he did. I'm just pointing out that in our new world there are new
and interesting ways to be a huge pain in the neck.

Here is his post describing what he did. It's fascinating, as are the comments.
