That is just how the system works, though, you commit a crime, you get convicted. Then you could argue that the laws should change. But I can't understand these kids(?): smart enough to hack a server, but not smart enough to understand the consequences? Presumably he is feeling invincible?
There seem to be a lot of people who might be willing to give him a second change even with a felony conviction. It sounds like you would? If he really is just a stupid kid, there might be extra laws for kids, and the punishment less severe?
Cocaine is an entirely different matter, because it only damages the user, not other people. Hacking a public server damages other people. How is that excusable? And he didn't just put up a powned message, either, he tried to make money. What's next, selling accounts to the russian mafia?
I mean I would agree with you that if you personally feel that the crime is not really a crime (as you might feel about possession of drugs), you wouldn't press charges. But I don't see how hacking a server with the purpose of making money could not be considered a crime.
