These ads may not be scams, but it certainly creates some confusion.

I am more than a little surprised by those defending Googles lack of action here. How hard would it be for Google to prevent ads from showing on the keyword Google Money Tree or Google Cash? asks Jonah Stein, who has written about the subject himself. It looks like the White Knights have prevailed though, because the organic results all appear to be in reference to Google Cash as a scam. As McGee points out, usually Google doesnt like these organized efforts to influence results, but perhaps considering the cause, they will let this one slide.
