The way I see it is just as it says. Advertisers bids will ultimately adjust up or down according the percentage of click fraud they are dealing with. If google is comfortable with the current fraud levels and they are taking measures to contain it, and advertisers are using conversion tracking and turning a profit, everyone is happy...unfortunately so are the fraudsters that are making off with the 10% to 25% margin allotted for click fraud.

Does anyone know if an iPhone would work on the moon?

Sure the phone would turn on and all, but good luck getting a signal, unless google's lunar x prize [webmasterworld.com] includes setting up an AT&T cell phone tower with a satellite relay to Earth as one of the 5$ million bonus missions.
