If you have access to your .htaccess file here is a great addition that stops 95% of site copiers and blocks 80% of uninvited bandwidth wasting spiders as well.
I can't take credit for it. It came from a thread in another forum. I have tested it with a user agent spoofer and it is very successful.
USE AT YOUR OWN RISK! and be careful when you make additions as wildcarding bot for example would block googlebot.
