We can see a number of cases demonstrating that there are many issues with delivering adult content in the Web. From latest, I would like to highlight following two:
New Microsoft search engine Bing.com is perfect if you want to see the porn multimedia: http://www.theregister.co.uk/2009/06/01/bing_hits_uk/
The ISP Triple Fibre Network has been closed by FTC for multiple violations, including spam and child porn http://www.ftc.gov/opa/2009/06/3fn.shtm .
Regarding last article: if you have the host at some hosting provider or ISP, are you sure you are safe? ISP can be closed at any time, and all your resources will be unaccessible.
