Practically, this is nearly impossible. Just think: How many porn websites are out there? It would be practically impossible to drop packets of every such porn websites even if you wrote an automated script to do so. Many filtering systems implement web proxy system with a generic list of banned websites and also make use of keyword based system. But again, even if the filtering systems implemented multiple level of blocking, people have found the ways to break through such blockings(as in case of cleanfeed). I've heard McAfee Web Gateaway and Barracuda Web Security Flex are good products. All I have to say is using iptables to block porn websites would not be effective. This site lists some content filtering softwares but not all. http://www.timberlinetechnologies.com/products/contentfilt.html
And remember security practice is merely a process of decreasing the probability of unwanted actions(& its effect) to the system.
