The popular DigitalPoint Ad Network has reached a new level of popularity. People are actually advertising it on Google's AdWord network for certain keyword phrases. The reason they advertise it, is because they get "referral credit" for everyone they refer. So the cost per click pays based on the rankings it produces organically for the user who is paying for the ad.
I believe the keyword this individual was bidding on was good cpm banner network, the ad does not come up anymore. For a screen capture see here and for the forum thread visit DigitalPoint Forums.
