Thz Max for your guide! Looks like it would be a better choice to go with YPN at the moment especially for lower traffic sites. To what I notice too, higher traffic sites would be on safer part in Adsense due to the percentage of fraud is too small and couldn't trigger Adsense alarm, thus making it safer for them. On the other part, for lower traffic site, even a small amount of fraud could result in higher percentage and thus trigger the alarm causing the account to be banned.
Really can't wait for it to out of bete as soon.
