I suspect if she is homeless, she lives in a shelter, as there is no way she could behave as she does otherwise.
A) Posts any time of the day or night.
B) If she were hanging in one place, she would have been picked up by now, meaning she has to be mobile.
C) No way an unemployed homeless person could afford the gas to drive her 'house' from place to place to chase WiFi hotspots.
D) She has yet to have her laptop stolen, or whatever she uses to post from. Nor has it broken/worn out. I care for my electronics, and she has had better luck than me in keeping them alive. As per point 'A' it can't be a library computer. As per point 'B', she would have been picked up by now.
E) She was horrified at the thought of other primitives going out to help her. What kind of bum refuses a free meal, or some drinking cash ?
F) How does she keep her posting device charged ? Her car battery would have died by now, as she is certainly out of gas and cant run it to charge it.
-- Which is why I suspect that if she is homeless, she is in a shelter, or maybe a mental hospital with an internet enabled rec-room. Otherwise she is an ultramole.
