Suppose I made an eBay account using "chris.gmail" as my log In Id , now due to my carelessness my eBay account got banned. Next thing you know, i am deleting cookies off my browser, getting a new IP and all that jazz. Essentially what one must do , before making a new eBay account , after their primary got suspended. Now I know I can never log into my old suspended eBay ever . What about gMail ? Suppose I log into my old gmail account [ chris.gmail ] with my new IP address, same IP i am using for my new fresh eBay account. If there any chance Google would contact eBay telling them " hey look! just so you know this guy you banned has just got a new IP , make sure to check any accounts that are using the same IP address , just incase he is back"
