I would not use the same name or address on 2 accounts. If one gets linked and suspended, the other will go down too. Just use totally different names and addresses for both accounts and you'll have nothing to worry about.
i would suggest reading the Stealth Book again. It talks about names and addresses specifically. You might also do some research in the forum, theres some good info about this. Good Luck!
I agree. I have two old original accounts in my name, one is a po box. as soon as i started really selling - once one got hit with violations the other one did rather quickly as well.
