I have thought that the concept of "porn star" or even porn-actress became useless with the transition from video tape to DVD and then free online porn vider sites. Today, any girl with a lap-top can shake her stuff or otherwise do her thing (or her boyfriend) and be viewed by every perv on the planet.
I am NOT a porn*star* however you can find my name on that site as "Kaycee Rivers"
Many of the providers to avoid a certain "branded" type will often avoid labeling themselves. Unless they desire to upcharge for the name itself. Instead of looking for a pornstar I would recommend you look for the sort of experience you are wanting. For instance a porn star experience. Then narrow it down by looks. If you just want the notch of a porn star there is one "Chasey lane" that travels around a lot and even sometimes works at the bunny ranch. Moderately affordable if you have low four digits to spend (I have seen her at high 3 digits as well)
Carmella bing used to travel as well. I met both of these ladies in person and they are incredibly nice with the libido's they portray on film. Carmella for instance was very much the PSE.
Sunset Thomas also occasional comes about but none of these are on eccie if I recall.. Check eros. Generally pornstar's are more inclined to advertise there.
Eccie is known for hobbiests and MOST (not all) pornstar's are not looking for a stable regular income of regulars rather they seek singular high paying clients.
