Google, simply take a sentence from it and put it in quotes and search for it. Such as you can find this post in Google once it is indexed by typing "Google, simply take a sentence from it and put it in quotes and search for it" in google. Hope this helps.

I highly recommend Copyscape as well. Good for you for getting on top of this. If you accidentally ended up with a scraped article on your White Hat page no one would believe that you weren't aware -- the "sorry, I just outsourced it" excuse has been so widely used by the illegitimate sploggers that, even if it's true, you'll still catch a lot of flak. So. Copyscape.
