I don't mess with submitting DMCAs through Google anymore. Using a formal DMCA notice I find that my sites get noticeable boosts soon after an infringing site or pages from an infringing site are blocked by the host. It might be imagination but I've done more than 20 DMCAs and see the increase in ranking nearly every time. However small, it is noticeable and there are no changes to the original site itself.
As far as authorship markup is concerned, Sorry tedster, I've seen sites eek past ours using our content adding markup dated years before the domain the content is on were even registered (Site says "Posted by admin 10-27-2008" but the domain was registered in 2010).
I do have a qualifier though:
If the site is a local site and it seems the owner isn't a webmaster and may have hired someone to build their site, I send them the notice first in a more personal manner "Hey, you have my content, here's how I can prove it and these are my intentions...."
If it's a competitive site that is obviously someone who scraped or copied/pasted from us and is trying to take a niche, I go straight to the host without warning to the owner.
I have no belief that Google can determine original authorship. If they can then they ignore it deliberately or by omission. We had content that Google didn't know about and now you can find map pages with the information we made public. Maybe they got smarter while we did the work, but that's not my opinion.
