I requested a DMCA with google to have THEIR pages delisted, and google said that I had not sufficiently proven to google that it was OUR content.
This is really odd. Google has never blinked at delisting scraped page I ask them to. I wonder what they look to for "proof" that you posted it first. Their caches? Something on the server? Please tell me merely sticking on a date, as I do, isn't enough, because anyone can doctor that, even in a CMS that does it automatically (I use Wordpress). I've accidentally scheduled posts for the time of the King John and Robin Hood before.
