OMFG are you guys serious... Like s0br is not smart enough to use a mailing center to ship his packages I can help you he used a mailing center in california. You can call and offer to pay/bribe them but they wont be able to help you. So umm GFYS the both of ya...
Or we could subpoena them. But if s0br is legit as you say, what reason would he have to hide his identity?
