I was thinking more like "of XYZ town" than anything about you personally. And since most of these are getting sold online, you want the duped buyers to report the sellers to the site where the books were listed. A bunch of one-star reviews for selling LFL books will tank someone out of abebooks or similar pretty fast.

You might even put a stamp on a sheet of paper with a note that it's in every book in the library to discourage the thieves from looking in the first place.
