Is anonymity only related to identity, and which parties are involved in a transaction? Could there be a way to leave identity and parties involved anonymous, yet track count and/or value of transactions without knowing what they were? If this were possible, some weighting could be assigned to reviews based on count and/or value of transactions, to somewhat combat a review bomber willing to pay for many small transactions. In a sense it would raise the cost of a fake review campaign. I bet if you gave users the option to have only count and value of their transactions public, in exchange for some sort of “trusted reviewer” status badge, that a significant number would opt in to it, because people like to earn badges and points for reasons more motivating that we intuitively think. edit: better yet, allow opt in to have your transaction count and value incrementee on a per transaction basis, so you could earn reputation power or not depending on the marketplace or persons dealt with. side note: I think the “free sub” episode on Seinfeld may have been the first reference to gamification mechanics on television.
