Want to catch people stealing your website content? Use an RSS honeypot: "his article originally appeared at [article URL]. All rights reserved. If you are not reading this on a personal RSS reader (such as Feedburner) or on [website domain], you are reading a scraper website that has illegally copied and stolen [website domain]'s content. Please visit [article URL] for the original version, along with all its comments.
This way, I could do a Google search for that text string (well, for a part of it -- it is rather long), and discover which websites were automatically copying my site's content."
