Pedophilia Guide on Amazon

I thought for a while about whether to make a post about this issue or not; it very much relates to books, but I didn't want to give it any further attention, like by linking it I was somehow doing what whoever decided to put that book on Amazon wanted. In any case, here goes:

Some asshat* decided to sell a guide to pedophilia on Amazon. They stopped selling it. Amazon has had issues with 'offensive material' before:

This isn't the first time Amazon has sold material that promotes illegal activity. It is currently accepting pre-orders for the hardcover version of I Am the Market: How to Smuggle Cocaine by the Ton, in Five Easy Lessons by Luca Rastello.

Nor is it the first time Amazon has come under attack for selling objectionable content in its store. In 2002, the United States Justice Foundation, a conservative group, threatened to sue Amazon for selling Understanding Loved Boys and Boylovers. That title is still available through Amazon.

In 2009, Amazon stopped selling RapeLay, a first-person video game in which the protagonist stalks and then rapes a mother and her daughters, after it was widely condemned in the media and by various interest groups.

I guess this is one of those 'buts' regarding censorship. Censorship is wrong, but I don't want anyone making money off a how-to guide to pedophilia. Is this a valid argument because of money changing hands, or am I just making excuses?
