I have worked in the area of content filtering for many years. Most of the application requirements have been for Pornographic filtering by NGOs, Government, Large corporate offices, educational institutions and home users. We have evaluated all types of software for Pornographic blocking and found that none really works for the reasons given in the different mails in this e-mail thread: URL, IP address blocking, text based blocking, etc are all faulty. When the government tried to filter on the Network by setting up Access lists, the network collapsed!
One set of software which works amazingly in LAN and individual home environments are Screen Shield and iShield from Guardware. This is very low cost for its flexibility and accuracy and has an amazing ability to not only block offensive images from the Internet but it actually scans all PCs on the LAN to detect and block JPEG, MPEG, AVI, etc (images and movies). This software does it by examining the images and using a sophisticated image processing, blocks the images but leaves the text (configurable). I have deployed this in corporate environments and in Universities and have seen Internet traffic drop to less then 30% and people become more careful of using office facilities for this purpose. In home environments, this enables one to safely set the blocking levels. I had earlier tried Net Nanny, cyber patrol etc, but the kids are too smart and use better evasive and bypass methods and these did not work.
