At first this made me laugh a bit, since hacking and piracy sometimes brings joy to me, being a pirate relative.
Then I saw Something's post, and I realized that you really shouldn't have done that. It's not about karma or any of that feng shui bullstuff that the koranese made to scare Americans, but it's just doesn't feel right in my opinion to take something from someone, especially when that someone has worked countless months, years even, in working hard to get that something that meant a lot to them. Think of something you own that is very valuable to anyone, like your computer, a PSP or your identity over your credit card even. Think about that, and also think having that something, being taken away from you. After working so hard to earn it, chores for money, working, whatever, it all gets taken away.
That's what you've done exactly to that person. I sometimes feel like an starfish when I massively flame idiots on the internet, but that's only disciplining idiots into normal people. What you've done is taken the glory and pride out of someone working very hard to earn something valuable, because you were bored and tried to show off in front of your friends.
