How to get a custom Activision username with symbols / invisible

(Credit to monkeyns, I did not find this glitch)

This is how you can have no name on MW, or the symbols below,

- Access the Activision website.
- Log in with the account you wish to modify.
- Access your profile.
- Access basic info.
- Copy this >ﾠﾠﾠﾠﾠﾠﾠﾠﾠﾠ< (Copy without the ><).
- In ID Activision, paste what you copied previously.
- Register your invisible nickname by clicking save and putting your password in.
- The game will close by itself if it is already open, otherwise launch the game.
- you can return to your old nickname at any time.

Please remember to leave thanks and +rep!
