You will quickly find out that the scrapers are coming from USA-based proxies, they pretend to be Google or Bing, they use an intermediary (say, Google Cache)... and so on, until you are tired of fighting them.
It's a losing game, unless you don't mind making it hard for actual users to view your content.
I agree with bobds. It's retarded to worry about scrapers. You're better off focusing on doing your own thing. Large sites get scrapped and cloned all the time. At the end of the day, it's better to be focused on what you do rather than the clones.
