Over the last 2 months my CTR has about doubled and my CPC about halved.
Could they be Smart-Pricing me for a CTR over 20% ?

Seems like it could be a high ctr. I get nervous when I see this happening.
On one of my sites, I recently removed all adsense and blocked a domain that was suddenly seeing unusually high ctr's. I have no control over people clicking, but of course you can't explain this to g. They ban first, and never ask questions.
