Gl man! Gonna tell us what method you using or do you have a secret one, and are you using somekind of proxys/VPS'es if so could you tell where did you get yours.
But does two wrongs make it right? ^_^
I'd suggest you to politely just e-mail him and tell that you have all his info and you're "ready" to use them for unwanted purposes... Imo you got the leverage here.
I'd like to buy a package #2 from you, alltough I'm new to all the VPS things so help is needed and I'm quessing that you're more than happy to give it. :P If you still have those left, could you PM me please asap! ;)
