A self-published guide giving advice to paedophiles that was on sale through online retailer Amazon is stirring up controversy, with some threatening to boycott the website. The Pedophile's Guide to Love and Pleasure: a Child-lover's Code of Conduct has now been removed from sale. But Amazon had defended the listing, saying it did not promote criminal acts but also avoided censorship. Amazon allows authors to submit their own books and shares revenue with them. Before authors are able to sell a work on the site, they are asked to read a set of guidelines, which bans offensive materials. But Amazon does not specifically state on its website what material it deems offensive, instead saying "probably what you would expect".
