Of course, that was never considered nor was collateral damage because the ethical justification is just a pretense to excuse harming others.
Your argument totally falls apart here, because you’re just outright wrong. There are a ton of kids who are curious would-be hackers that turn away from the dark side forever after getting pwned while trying to do something sketchy.
... How do you know?
This is not certain.
It taught them a valuable life lesson about trust and humility, and maybe even ethics and the risks of criminal activity in very mild fashion. Recovering from being hacked might stir feelings of empathy for their victims and lead them to learn valuable forensics skills.
Stories like this are part of the personal evolution of a lot of white hats. I think aaza did a real service to the world.
More to the point, I don't understand why you want to spank them for this now. Kids do stupid stuff and this is far less stupid and dangerous than a lot. Indeed a lot of no-effort hackers get burnt on this stuff and stop. I know people who tried and failed. Adding peril to the process scares off a lot of would-be bad behaviour.
