No. That's one thing a lot of people think that are legit or actually work. Generators. 9.9/10 times they are FAKE. Why? I can make a simple generator in VB that generates RANDOM letters and numbers to a certain character amount. 9/10 "generators" are also either malicious or backdoored. The reason why we can't just "generate" codes to Itunes? Because, each key is VERY different, and it's almost impossible for a person to code a program that can hit one of the keys right on the spot; not to mention the fact that the key has to be BOUGHT and paid for - for it to be activated and available to enter into Itunes and used as money.
