Everyone here is probably fairly well aware of how easy it is to compromise accounts on these online services. I hope most HN users recognize that the appropriate course of action after hacking a service like this is to notify the account holder to help them improve their security before revealing the details.
If you really aren't doing this for profit, and you really don't want to hurt the victim of the attack, (as Hacker Croll claims) then don't disclose the information you stole to major press outlets. This attack is really in poor taste, and I think we all of us here at HN should recognize the difference between pointing out the dangers of the internet and being one of the dangers ourselves.
