I called ebay and let them know whats going on and that he uses differant account names. When I asked if they wanted to know all of them that I have found they said they didnt need them. Said they would probably start checking his IP address and any accounts related to it. That way even if he is using a differant email for each account, as long as he is using the same computer with each one they can tie the IP's together. I let them know about the paypal dispute I had also that was closed in my favor. So hopefully this little prick gets shutdown.
If you look at his feedback its all as a buyer not as the seller. So he must have just started trying to do this, or this is the first time he has used the latest account as a seller.
