I guess you mean 'to adult sites' - not 'from'.

There are a few projects that collect URLs. In short terms and IMHO:
forget it. There are thousands of domains registered daily. The job of
blocking all URLs which fit your category is such a stupid job that it's
only done in commercial software.

I personally like 'WebWasher' because they have a team of students and
housewifes which do nothing but surfing all day long categorizing URLs.
However there are more vendors. If you want to be serious about URL
filtering you will have to invest money.

If you can't spend a buck and don't want to be that serious you may go
with 'SquidBlock'. That's an automatically generated list of URLs from a
web spider. From my experience this works well for 95% of all sites but
you will have a lot of trouble with the last 5%. You may try this at
home but if your job as a net admin is to block access to illegal
content then you won't be happy with this.

How did you get the URL database from CyberPatrol? If other know the
URL database then who wil buy their software? Companies will do anything
to protect the URL list.

My predecessor at my job also tried that. Good luck. ;)
