It depends if they ban by your mac address, which an automated ban would not do, that would be after a GM investigates you. I have had non botting accounts banned, for "association to exploitive accounts," yes ASSOCIATION. I even opened a vanilla account, and never logged on it, they closed it for association too. It's hit or miss, but if you fight a ban or give them reason to investigate (sell a lot at once) then they might link accounts.
And yes they do link accounts by mac address, had 10 accounts drop at once one computer, then through similar account info they knocked another 5 on a computer next to this one. But I sold about $1K USD in one night so I expected to lose an account or two, but this GM decided to look a little further.
GL I wouldnt chance it, at least use a different computer, and dont transfer gold between the accounts, I wouldnt even friend each other. Even use different contact information.
