Im not quite getting your point here, about them being so young?
Delve outside of runescape and you'll find most of the arrested HACKERS today are no more than 25 years old. Not skiddys, hackers, taking down corporations.
Age is meaningless at this point, people have learned greater things at a young age than a 40-50 year old CEO of a security firm could ever know.
The two bot "geniuses" were probably bot developers long before the began work at JaGex. Either way was a really good watch, and I don't think people truly understand how much they are doing. Seems like every time I log out and come back it says please reload the page Runescape has updated.
