Yea, but you're acting like piracy is world's current number 1 problem/crime. The person who contacted you is most likely underage, which means that their parents either don't want to buy the game or they don't have money for it. And since the person is underage, they can't get a legal job to buy the game. Kind of a my story, but that's about to change in about a week because I'm getting a job, finally.
And when it comes to tracking down pirates and catching them, it all depends on ISPs whether they care about it or not. In most cases they don't care because they don't want to lose costumers.
