It is pretty clear that the hero account was either purchased and/or stolen. If it was purchased then the price was most likely less then the 1 BTC that he stole and he ended up selling it to someone else to recover the price he paid to buy the account.
Aahzmundus tells me that indeed his account was stolen, presumably as a result of the recent forum database leak.
I PM'ed theymos asking him to reset the password but didn't hear anything back.
I left negative feedback on Aahzmundus' account saying that the account is compromised.
I think the hacker sold the account to cryptoforcause for a low price saying that he don't have signed message or it is also possible that it was already known to cryptoforcause that the account he is buying is a hacked one.
And purchased it with an intention of doing a scam what he did.
