This is almost becoming a full-time endeavor to weed out the bad guys.
Thanks for any help.
Some of us will create a "bot trap" web page that is linked to from our index page (with an obscure link that humans wouldn't click), but disallowed in our robots.txt. This bot trap page will be a PHP (or other CGI) script that will log the access by the "bad" bot and possibly ban the bot from the server.
