I've seen several hack cases and it's not even funny how a user would be up, day and night just to create a reputation and it's taken away just in a moment;
What sorts of hacks are you referring to here on bitcointalk? I wouldn't sweat it too much though. Even if some joker manages to hack into someone's account, that dont mean the site itself is vulnerable and folks gotta be responsible for their own security - can't expect Bitcointalk to babysit everyone's account.
