She probably quit/retired... the last time I emailed with her, she was supposed to be attending the Exxxotica Expo and I was trying to book her (this was about 2 years ago -right about the time frame that reviews and twitter posts stopped).  She blew off Exxxotica... and was supposedly just doing bookings in her hotel room... and then flaked on at least some of the bookings.

It wouldn't surprise me if she decided she'd had enough of the adult industry and just went on to something else.
