It's intellectually dishonest to equate Google with "scraper" sites. Google is a search engine that adds value to the Web for both users and publishers with its search results. In contrast, "scraper" sites are parasites that feed off the results of legitimate SEs while cluttering SERPs with pages of secondhand search results.
As far as AdSense is concerned, the argument that "scraper" sites are equivalent to Google is irrelevant, because the AdSense program policies explicitly forbid exclude "made for AdSense" sites. Publishers who place the AdSense code on such sites are in breach of contract, and Google would be justified in terminating their accounts even if "scraper" sites were inspired by God, blessed by the Pope, and sanctioned by the Sierra Club.
It does in the case of AdSense, unless you're talking about the new "AdSense for search" spinoff. The main AdSense network is called "AdSense for content," and Google's descriptions and program policies make liberal use of the word "content." Before placing the AdSense code on questionable pages, you may want to review the Google AdSense FAQS, program policies, etc. at:
