Dom was born in 1995, in 2011-2013 he would have been 16-18 when this alleged "hacking" occurred (not a member on hackforums so I can't see the post or the archive posts you have provided, I can however 300% zoom in on the images you posted to half read their contents). Let's be honest; what teenager hasn't hacked a poorly secured website, DDoS'd a website, dropped malware onto a terribly secured system, or engaged in other questionable activities online if they are gifted in computers?

Some of my friends from high-school did these sorts of things back in the early 2000's "hacking" the admin password for the school library, dropping a key logger on the system, then screwing with whom ever was unfortunate enough to use those computers. Many of those friends went on to college and university for computer programming and other computer sciences and got good. high level jobs as a result. The high-school didn't offer any computer courses remotely close to the level of skill these friends had/have, the programming courses were basic and offered no challenge to them, no one was there to teach an "ethical hacking" course with dummy systems to test out. I imagine it would have been similar for Dom during high-school. If you want to learn a system one of the best ways to do so is to break/crack that system.

It seems like a natural outcome for someone interested in computers, computer sciences or cyber security. Many hackers hired by top level security firms or governments get their starts this exact way.

Also many countries do not enforce "adult" laws on minors, Italy is one of those countries that has punishments for ages 14-18 but a person is not deemed fully criminally responsibility till 18 in most cases. additionally some countries do not keep record of crimes committed before the age of "adult" or "age of criminal responsibility" (https://en.wikipedia.org/wiki/Defense_of_infancy)

I guess I just don't understand why a potentially bored, computer gifted teenager, being a teenager, is the cause of doom and gloom.
