Yes, she is an extra who appears in porn films but doesn't actually part of the "action".
A while back, someone tracked down her social media account which included stuff like her real name so those references were removed.
Unless things have changed since then and she now has a stage name, let's not go down that route again please people.
When helping to ID babes, it should be with a view to their performer names rather than their real-life identities.
That name of Luna can be taken with a grain of salt unless she happens to be going by a stage name now. I guess the girls in that video could call themselves whatever the hell they like given they are playing a small part.
