You don't need the list of potential scrapers, it could apply to anyone who published the same content after.
The issue though is if you write a blog and don't know to do this, the scrapers do know and nick your content and inform Google of "their" new article. At that point you're now seen as a scraper for an article you actually wrote because the real scraper plays the game better.
And that's the real problem - the scrapers play the game better than the rest of us because they can commit larger amounts of time to it (not having to waste time writing actual content and all).
