Accidentally, my developer put a 5 second refresh tag on all my website ads (instead of the required 3 minutes auto-fresh on Tribal Fusion ads) and got all the ads to refresh every 5 seconds. This went on for the whole night (9 hours) and next morning I discovered that my adsense earning had doubled and pageviews were 10 times more. I was expecting some policy violation notification but didn't get any.
