Sure -- I guess in general it wouldn't be click through rates, but click through rates on pages arrived at via search traffic. Obviously a community where members of a niche frequented a given site and clicked on related links would be different. And you're also right that using the word proportional was sloppy -- what was meant was correlated in assumedly meaningly ways. Really this was the front end of the question of, "Could some application of (negative) weighting based on the combination of search + adsense clicks help to remove some of the spaminess that is currently being lamented on the interwebs?"
