That is already discussed in forum .. see --->
Blocking yahoo messenger in squid
There you have to take 3rd last post by user ilias.

also blocking porn site is very easy, use url_regex

See the post here by gauravbajaj -->

You can actually block every website having word like "porn, nude, xxx' etc in its url.
