It would be better if all players know the redeems. The most codes have only 50 redeems and then people post them in Twitter where they are gone in 5 minutes. So if I find a code with 50 redeems that is 30 minutes old I can be sure that it is expired and do not have to log in and out. 90% of code creaters do not add the amount of redeens by themself.
