Can i have 2 battle tags to one account?

As this thread seems to be getting off topic, I'm going to lock it, but wanted to provide some additional information.

Only one BattleTag can exist on a Battle.net account. Also, while account sharing is prohibited, there isn't much we can do to stop people from sharing their account information (if that is indeed what is happening). It seriously puts the accounts at risk for compromise, and may limit what assistance we are able to provide in such cases. If you have additional questions or concerns about this, I recommend opening up a ticket on our support site and talk to our Game Masters.
