Funny how the title says "men" and then you discover that those are just two kids of 19 and 18 years old. I was expecting to read about some serious cyber criminals...
So... you're saying they shouldn't be considered adults at age 18, then?
18 years threshold is just an odd convention. Biologically it's closer to 12 but the legal and cultural threshold varies wildly all over the planet. My rule of thumb: if you don't have to make a living - you're a kid. Enjoy it while it lasts.
