Google recently launched pay per action for all US AdSense to try out.
Reports from DigitalPoint Forums show that some publishers are being opted into the program automatically.
One publisher said that Google emailed him saying he "has been selected to" be automatically entered into his ads showing Pay Per Action ads. Within five days, Google will dynamically replace 5% or less of his normal AdSense ads with Pay Per Action ads.
The only way for him to opt out is to email Google, requesting to be opted out.
People find this outrageous. Why would Google force publishers into this program, when it is clearly available for them to select under the referrals section of AdSense? Why require an opt out, just let them opt in?

This move will eventually move google away from lawsuits due to click fraud. Good for google, good for advertisers and it puts the pressure on publishers for attracting purchasing type of consumers. We have turned off all our Pay per click content ads and are 100% pay per action.
