It's also possible that you use a weak password and someone bruteforced your keys.
he did something he knows he shouldnt have and now its come back to bite him in the ass and hes pissed about it,\
Its his own damn fault!
If he's telling the truth about this which I am not sure, ........ It's not even worth the post. Bye to this OP.
call sony 1-800-345-SONY and they can deactivate all 5 of your ps3's. If they give you a problem and tell you no they can't then you can ask to speak to a supervisor in their "Foster City" location (they have 2 call centers, one in las vegas, the other in foster city).
Also note the foster city site can only help you Monday to Friday
This is the best advice in here. I am going to lock this thread as it has been answered.
