"ClickBank’s proprietary tracking methods are considered a trade secret and cannot be shared here." Eww,,, they got a top Secret NASA style of tracking method that they cant speak about sounds like an excuse. Its impossible to track affiliate commission accurately if the cookies are cleared and yet "clickbank makes miracles and will make sure that affiliates do not loose their commissions even if its impossible - WITH THEIR TRADE SECRET METHOD OF TRACKING..." .. I tell you, what about making at least the normal cookie based system reliable to get started!
