I haven’t actually seen this metrocard scammer since the last time, but I discovered this article that says that indeed this is what scammers were doing with the 1-day fun passes. They bought a whole bunch of them and sold the swipes. Because of this, the MTA decided to get rid of them entirely which sucks for tourists and people like me who are unemployed who don’t use the subway often enough to buy an unlimited card. The 14-day pass is also no more since the beginning of this year. Thanks MTA.
