Maybe the truth is, stories about click fraud won't go away....HIghlights:

A lack of clear standards for determining what is a fraudulent click, or some sort of third-party clearinghouse to monitor the situation, means some advertisers believe they can't do much more than head to the courts when they think there's a problem....

...Some experts say the solution is to have an independent auditor that would use data from the search engines and advertisers to determine in a neutral environment whether clicks are fraudulent.

Google and Yahoo, however, appear reluctant to embrace that idea.
