A lot of bloggers have had trouble with people all those "splogs," those sites that copy your blog content and then rack up the revenue from google ads. I know quite a number of members of Food Blog S'cool have had this issue.
I ran across the mentione of software (or an account?) that can help you track the sploggy things over at Tech Blogger Scoble's blog. It's called Blogwerx Sentinel.
From what I can tell, the basic version is free for now.
