Thanks for the tips guys. I built my site to be simple and easy, I considered flash but I don't want to alienate some of my clientèle. Of course, that wouldn't protect text either. My entire site is copyrighted, all images and text were created by me (as was all the code), so I guess my only option is to find it when it happens and ask to take it down, then have my lawyer write a letter.
I do watermark all photos, but did not to the images I created for educational purposes. I will. Thanks for the idea.
FWIW, I believe there is a site builder building these generic sites for detailers and using the same stolen content from me. I'd love to find out who the guy is and what he's being paid for these stolen sites.
