I use a product called Fairshare to trace where my blog is being reused. My blog is licensed under CC, so I am actively promoting reuse, but this incident is just kind of weird. Check out my post on and this post by someone else.
It appears it has a bot, or equivalent, that will read text and replace words with synonyms, probably so the works aren't identical and thus it's harder to find them scraping your blog.
So here's the irony. This scraper is actually legally entitled to do what he is doing so long as he licenses his derivative work under my original work.
Presently, I'm not sure if I care enough to do anything about it.
