Did you read the Mea Culpa? Unless Mr. Winter is lying, Zak's question still stands. It seems like there is a potential for injustice when the reviews are held in secret like they were. All Google put forth was that there was a risk of generating invalid [click] activity.

As one who, like you, pays for that invalid activity I am glad to see Google do what they can to stem it.

But it gets very serious in my mind when they can also take the cash from the account. They should be required to show explicitly their justification. If that means that their business has to change because their algorithms are exposed, so be it. What they are doing does not seem to be a fair business practice to me, and I worry about the precedent they are being allowed to set.
