There is a couple on Mygirlfund and a couple on Cam4 that I have personally interacted with. Not going to name names as they are kind of wide known and may not want a bunch of people flocking over there and bombarding them.
80s/90s fetish model Gina Carrera did tickle work for Harmony, Cal Star and FM Concepts is also on steamate.com under the name "julieray". Amazing that some of them are still earning a living off their looks as they hit 50.
