I have done this with a couple of models, popularity based on replies per year and how it changes over time. The ones I did with Lucie Wilde and Stephanie Fox showed how their popularity was astounding to start with, but tailed off immensely once they stopped modelling.
With Samanta's case, when this thread first began, she was a relative unknown, but over time once she became more established (posing for Score, DDF, Pinupfiles and Yesboobs etc) her popularity increased, peaking with last year when her wonderful boobs got a pregnancy boost. Her popularity has waned a bit since giving birth, with her breasts shrinking somewhat from her bountiful times last year, but still more popular than her first two years on the BEA.
