Google's got some sly built in too, they know that spammers will do what they must to knock down competitors. I'd bet dollars to donuts that the 'reporter' of spam is also considered a potential abuser.
Google will put ALL data to use, even the stuff you're not asking them to. Still, I'm all for anything that keeps spam from floating though I'm too busy to police the web for google.
