Now I can ask a question I’ve always been wondering about: is there a way to design tamper proof ranking schemes ? Google keeps their ranking scheme for pages secret, because they’re afraid of users gaming the system (pun not intended!). There are other settings (Digg etc) where the ranking provides value, but the system designers need to play some kind of game with the adversary to prevent the system from being corrupted.
Does AGT provide any kind of answer for this problem ? I was browsing the book, but didn’t find anything directly related.
