How would that help? If the NSA tracks a billion accouns, how is even a million fake ones going to make a difference? I'm pretty sure "spam" is not a new concept to them. If they want to look up any real person, they'll still be able to find all their email/IM accounts. If you include a way for the recipient of an email to tell "fake" messages from real ones, then the NSA will be able to tell as well.
