You will not find him on facebook, or myspace or any other networking type website.
I have heard that he is a paid member on "Unicorn Fancier.com", and "Butterfly Affectionado.com," but those are unconfirmed reports.
Rumors speculate his name is actually Tom, or Paul, Or Nancy. not sure if one is right, but its as good a place to start as any i guess.
Lupin doesnt really exist. he is a fictional charecter that was created by a former moderator who shall remain nameless, but who's initials are MG something.
Oh, I can be a flower, a werewolf, a professor, a clever thief or a guntoting fictional character. Pick whichever you want and I can transform easily into one of the above.
