How can I disable certain pages in a dynamic site

I have an auto-updated youtube api website where the site urls are always in the form

www.mydomain.com/video/yt.php?$TITLE

or

www.mydomain.com/video/$ID/$TITLE.html

where $ID is the video id and $TITLE is the video title.

Now I want to disable/ban any page that the $TITLE contains a certain word (e.g. sex).

Any idea how can I do that?

You could use regular expressions to do that.
