no as a "code generater" has about as much chance on getting a real code then u guessing your friends 64 digit password as psn codes are not activated untill you buy one

1.Wrong section.
2.It would be close to impossible to get a PSN code generator because you would have to figure out their algorithm which if you tried to do, you would have to buy a bunch of PSN codes online within seconds of each purchase hoping that no one is also buying at that same moment. And then you would be analyzing the codes and patterns which would take you months maybe even days with a computer program that would scan the codes. And what if they change there algorithm slightly every day.
3.If you have done all the above and you have figured it out, then when you start to use it and they (Sony) see mass purchases from non-existent or future codes they will notice that something is up then they will look at the accounts then addresses.... You get it!
