Here is the update, I guess Google usually make somethings unclear of the time: Is this the real thing we are looking for?
not at all! This means publishers will get less money per referral until XX days. Maybe a bit like smart pricing for adsense ads. It's a term to justify paying you peanuts per click/action. But anyway, those referrals need to be improved before I resume using them. Only some google products work for me.
