He states didn't even upload the site till dec. 15th and
had 35k uniques, over 500,000 page views, For a total of ~5k ad clicks.
Very very impressive, I still find it hard to believe. Looks like that kind of traffic on a new site would flag the account to google. He described his methods. Google has stated no trick clicks redirects and so on.
