I've sent hundreds of DMCA complaints to Google for Blogspot alone, and it doesn't begin to touch the thousands of full-text scrapes and article farm replications some of my more popular (pre-Panda) pages attracted. Google has had their head in the sand about duplicate content for years, always denying it's a problem and then suggesting it's easy enough to fix with DMCA complaints. I'd like to see a Google engineer sitting in front of a screen all day cutting and pasting URLs into their DMCA form.
The ironic thing is that pre-Panda, I had stopped chasing infringements because Google had learned to ignore them. They unlearned it overnight last February. My guess would be that they don't know (or care) that some high quality sites are built around a small number of core pages that each take weeks to create. They find it easier to assume that high quality sites mean very large numbers of passable content that nobody would bother duplicating.
