By the way: I'm perturbed by this situation because this isn't just a garden variety scraper with a blogspot splog making money selling google ads. This appears to be a "hot new thing" with some venture capital funding and which is selling "premium memberships" to people who use the service. I really think it's important for these "hot new things" to understand that if their "product" is -- essentially-- pulling together content others created and putting a nice bow on it, they should approach the content creators with a monetary offer. The pretty bow is nice and everything-- and it may well be that the pretty bow makes customers willing to pay for product. But still.... In this particular case there actually is a principle involved.
