Completely Remove your Activision account

How to remove your Activision account

Sadly, Activision does not allow you to completely Remove your Activision account
We suggest you Obfuscate/Randomize your account which basically means logging into your account and simply changing all of your real info to random/fake info since they do not allow you to remove.
Currently, there is no way to delete your Call of Duty account. If you wish to start fresh you may remove all of your personal information and create a new account with a different email address. ” http://support.activision.com/articles/en_US/FAQ/Deleting-CallofDutycom-Account/
