This affects the Call of Duty community as some hackers are impersonating the "JD 2020" Gamertag, which is the Treyarch community manager's Gamertag. They are then tricking users into sending them money, Microsoft Points, or personal information under the pretext that they are a developer and will reward you with something (i.e. flashing clan tags, Map Packs, etc).
The vulnerability is strictly a cosmetic hack / mod which affects only the display name; people's accounts who are impersonated are actually completely safe & secure. Microsoft has been made aware of this issue and is investigating it as we speak.
In the meantime, it is important you understand myself nor any representative of our games will ever personally ask you for money, personal information, Microsoft Points, etc in exchange for anything. Any and all transactions on LIVE should take place via the official Xbox LIVE Marketplace.
