Default how to block adult pages

I have installed squid 2.6 and OBSD 4.2 with SquidGuard. The blocking
the url's and domains works great.

How block pages, not included in blacklist by word-index like: rope,
se..., por... *se..*, *xxx*

Thanks

You might try DansGuargian

Picking keywords is extremely difficult. E.g. blocking escort services
but
not Ford Escort dealerships. Some words are obvious, but others have
multiple meanings based on context and must be used carefully
especially
with wild cards. Lots of programming pages use XXX in examples.

excerpt from http://www.faqs.org/faqs/unix-faq/shell/csh-whynot/
Maybe you want to pipe stderr to a command and leave stdout alone.
Not too hard an idea, right? You can't do this in the csh as I
mentioned in 1a. In a Bourne shell, you can do things like this:

exec 3>&1; grep yyy xxx 2>&1 1>&3 3>&- | sed s/file/foobar/ 1>&2
3>&-
grep: xxx: No such foobar or directory

So it is a daunting task this filtering business. You will invariably
have
lots of false positives and should watch carefully to create a white
list.
