I'm surprised to see commenters comparing use of made up personas to lying. There're communities that create/change their personas to match how they perceive themselves, encourage their members to experiment with presented identities, and expect the society to respect and accept presented personas without questioning. I'm totally OK with that. How is this different from presenting oneself as an alter-ego though?
