I think Blizzard would find it unacceptable to use a fake name. If other players knows our first and last name and they know we pissed em off at some game. They could literally tried to track us down and kill us?
Oh yeah. Did you guys read the Battle.net Terms of Agreement? That of which encloses this part?

That's a very common term of such agreements, actually. It's partially necessary to be able to use chat logs for moderation and legal proceedings. Blizzard also reserves the right to terminate your account at any time for any or no reason, with or without notice. Actually, it's not
account, they own the account, the items, and anything related to it. Most MMOs work this way.
