I must admit I've seen a big drop during the last three months. Which is interesting only because there has been a corresponding, though dramatically unbalanced INCREASE in bid amounts for localized Adword campaigns.
I will have to have a look and see if the unpaid clicks have increased during the same period for each site.
I hope it's fluke, but the Google TOS in conjunction with the possible trend is a little disturbing. Fingers crossed I'm wrong
