Amazon pushing porn?

New users of Amazon.com's search engine A9.com may get an eyeful if they're not careful.

A search for an innocuous term such as "Frontpage SEO" will call up images of nude women on the first results page, alongside Web search results for Microsoft FrontPage software and links for data on search engine optimization (SEO). A9 by default includes images with the search results, but why the porn is showing up is unexplained.

People can filter "mature" pictures from A9 or close the column altogether. But even with the image-filter setting on "strict," pornographic images may seep through. According to A9's site: "Note: Even with these settings, it is possible for mature content to be displayed."

Note to self: Don't use A9 at work.
