Daphne Rosen was a Massachusetts based escort who was active on UseNet (pre-web for you young'ns). (No, I never saw her.)
At the time she was paying her way through college and was a smaller BBW. After some time off, she re-appeared slim but curvy, with implants to keep her breasts the same size as before the weight loss. She then moved to L.A. and became a porn star, and has had various cosmetic surgeries over the years. Her breasts kept getting bigger and bigger, and now she now is in the PAWG category (Phat Ass White Girl).
I found a slimmed-down-and-moved-to-LA video:
