Oh I don't track the MAC address for ebay. I need each MAC address in order to receive the exact same IP address per account. Each account I have has a specific IP address associated with it, but in order to retrieve the same IP each time, I need to know the MAC addy. I think this is a good tip for those of you who have dynamic IP's!
So sneakily enough, I think it makes it looks like each account keeps logging in from the same PC  |
