Amazon Mixes Porn with Standard Movies

Two things here: Amazon mixes porn with normal movie releases and there is porn on BD? See images below.  The 2nd image shows Pirates 2 mixed in with a search that delivers new BD releases. The last image is a search for Pirates. I can picture it now,"Mommy!! I want Pirates of the Caribbean!!"...............

Now I did notice that Pirates [I] was labeled R, but wouldn't you think that anything that is blatantly porn cut down to an R rating should be filed differently?  Pirates 2 doesn't seem to show a rating.

Chris, a frequenter of useful information like this tipped Amazon to see what their opinion on this was. They forwarded him off to another department. No response as of yet.
