I agree with PersephonesMommy, but, I know that Amazon does sell pornography. and it is easy to acess.

But, I think you need to take a re-check on the internet. It's just as easy for your children to click that link on Amazon as it is for them to click on a link for hardcore pornography on any other website. Half the flash game websites out there (That ALOT of young children frequent) are littered with pornograpic ads and such.

Use a filter. It's not that hard.
