Plausible deniability
Develop, within the porn industry, an arrangement where the body is provided by one person, the face by another -- with the upshots *cough* being that both the body-providing individual retains anonymity -- is thus spared public notoriety -- and the face-provider -- who could even contribute via 'face-capture' shooting -- is known not to have engaged in whatever 'sex' is portrayed in that film? It would create a remove, or distance, from the tawdry aspects -- if any -- of in-frame participation in porn film production.
