Any kind of paying for this kind of junk, whether it’s prepay or not, is a waste of money and people should just stop doing it. There are far better things to do with money than to buy some digital thing-a-ma-bob that is useless and can disappear any old time at the whim of the web site owner. I mean, I could make the same argument about knickknacks, because they’re silly and collect dust. However, a web site can’t remove them from your house. So, even a knickknack that collects dust is a better purchase than digital coins and awards and all that other bullshit.
