And it slows down the server substantially, I dare say

I started on the treacherous road of blocking sites, and
eventually gave up, as there were just too many. I found a
better solution was to use proxy authentication once I noted
porn sites showing up in the logs. People came in one morning
to find they needed a password to use the proxy, and some of
them discovered that their password didn't work. When they came
to find out, I asked them if they'd been to any sites not
related to research and/or coursework. Funny how most of them
went real quiet :-) Anyway, once the word got around that I
do read the log files and could tell who was going where, the
adult sites started dropping out of the logs. It seems people
would rather keep their accounts.

You may not be able to do this, depending on the amount of
security, etc, you have at your site. We have only one machine
that can talk to the internet, so it's easy here. What you may
also like to consider is blocking sites like persiankitty, so
while they can still visit adult sites, it becomes a little
harder to find them (although not much)
