She's probably not going to go to the authorities because this arguably the hardest type of rape to prove, because the physical evidence wouldn't mean anything (especially if the sex was rough and consensual to start).
And this will absolutely hurt his career, as there are going to be directors that refuse to work with him after this (either because they want to themselves, or because social media pressure will force them to). He still has his website/production company to retreat back to, and he'll probably still be able to find performers that he knows personally that will work with him (and new girls who don't know about all this), but his days of being the biggest name in porn are pretty much over.
Edit: Especially given that a lot of his work comes from places that like to consider themselves female-friendly or are actually run by women (X-Art/Collete, EroticaX/Mason), and those are the consumers that would react most negatively to this news.
They booked him for obscenity based on a scene that the female performer completely consented to being in, and use the "local standards" guideline to get him. It's why there are certain places in the US that you can't actually get porn shipped to. They tried to do the same thing to John Stagliano over a trailer to one of his movies viewed over the internet, actually.
