Also, I haven't really seen any other posts about str0ke's death, other than ones linking to bl4cksecurity or mentions of it quite a while after the initial post there.
It's not that I would consider it a hoax, but it highlights one of the oddities of pseudonymous culture. First and foremost, I was under the impression he was in his late 20s from his profiles elsewhere on the web, and the link says he was born in '74. Again, pseudonymous culture means that data could be false, accounts could be impostors, etc.
