Sadly, these spam blogs, or splogs, have been around for a long, long time. At least a few years. I've been battling them myself and helping others to do the same.
If they are using your content without permission, regardless of whether or not they link back to your original post, you can simply file a DMCA notice with their host and get the content removed. You can also report them to their advertisers and see about getting their funding cut.
If you need any help with that, let me know and I'll gladly do what I can.
