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?
