PS3 Hackers Can Now Unban Themselves
According to Destructoid, hackers can now apparently unban themselves. Even more disturbing, those users can even ban other players, provided they have access to the victim's console ID. As one hacker said last month, "The complete console is compromised – there is no way back."
And if you don't know this by now, don't give anyone access to your PS3's console ID. Seriously.
