I have a theory on Adsense cap for CPM

Let's say Adsense put a cap on a account for CPM based on weekly or monthly average CPM. If you increase clicks sharply, you will not get tons of money immediately because your CPM is capped by the say, 7day average CPM. By doing this, Adsense wouldn't have to pay for huge spikes of fraudulent/suspicious clicks. If it turns out to be legit, then they can dump the extra clicks at the end of month. Otherwise, Google just pays less CPC for more clicks so that the CPM could balance over the weeks.

How do I know it?

I have a few web sites on my Adsense account and one of them is unstable due to inappropriate database size or setting. It went down for a few days several time for the last year. (I had Adsense Account since June 2003).

The site provides about 40% of impressions and 10% of clicks and 10% of Revenue. Theoretically, if the site goes down, I should lose only 10% of clicks and revenue, right?

However, I have been losing about 20-30% of revenue due to similar CPMs before the site's downtime. That's why I think Adsense put cap on my account's CPM so that it may look normal when there is fluctuation in number of clicks. But If I lose 40% of impressions, there should be huge jump in CTR & CPM because the site's gets low CTR/CPM/CPM.

It has been a few times already so I am convinced that there is some kind of brake or balancer to make the stat look normal in terms of CPM.

This is only a theory, I know. If any of you have similar experience or any evidence for/against the argument, please share with others.

If Google does this, and I agree that they do, why are they banning even honest webmasters from the program? Its like, they make sure if the clicks are higher than the average, they will not pay you for those clicks, but they still ban some webmasters.

Right. That's just a precaution. If they determine that there was a damage to the program, they will terminate the publishers. Until then, they will have to use some measures to minimize the damages to the program.
