I haven't followed it, but did a quick search after your post. My take on these guys has always been this; what a huge waste of talent. We need people with these skills doing white-hat work and preparing to defend us against the Chinese government hackers, not wasting time harvesting email addresses for bragging rights. There is a right way and a wrong way to do penetration and vulnerability testing. The right way benefits everyone, the wrong way only benefits the hacker.
