Not in the trivial case. I meant most porn sites. All you have to do is use a reputation service and block uncategorized sites. Cisco OpenDNS actually offers a free DNS resolver that filters out most porn sites.

Also,surprised at the amount of responses on HN today that presume details....

This is what I was thinking of when I said "dealing with false positives"; those services make mistakes, and haven't hit every site.

I don't think anyone aims for perfection but a 90%+ true blocks and less than 5% false would be a high standard.
