If they copy any of your content, then you can send a DMCA notice to their ISP. And if they're doing what you say they are, then they'll do that soon enough. You may be able to figure out who their ISP is using tracert. You can also notify the sites they're plagiarizing from, and get them to do the same. If they file a DMCA counter-notice, or pop back up on a different ISP, then you'll have to go to court to get rid of them. That might or might not be worth it, depending whether they have money to sue for, how difficult they are to track down, and how much your lawyer charges.
