I think most that use their real full name, didn't so much make a decision to, but backed into it via regular modeling, nude modeling, adult movies.
I suspect thats how it went with Linsey Dawn Mckenzie, Gemma Massey & Natasha Marley.
A lot use their real partial name; Ginger Lynn xxxxx, Julia Ann xxxxxxx, Stoya, etc.
Ditto for Kerry Louise (Love)
