Being on an alternative account does not make anything better. They will permanently ban all accounts located on your IP address if you somehow were to hack a Domino Crown into your inventory. If you use a VPN, they can track down all of the owners of the exact Domino Crown you stole and terminate you that way.

My advice is, don't even try.
