I don't know if the whole debate about whether or not Trillian is a real person is still going on, but coming from me (and I still semi-hate FCC) I can confirm that Trillian is in fact a real, bonerfied, woman. Kinzie and her used to talk a lot, mainly about similarities and differences between me and Kesh's pecker size, but she is real.
However, the potential usage of her account for other means is highly possible, and does seem suspicious some of the activity that's been pointed out. That in itself is kind of fishy, but as Sandy said "Good luck proving anything." (or something like that)
