I don't know how true it is, but years ago I exchange DMs with a guy who apparently knew people close to her. He told me there was a lot of shady shit behind the scenes. She didn't liked working with Jason Luv and almost sued Markus Dupree. Luv was too rough with her and Dupree straight up abused her. You kinda can see it as well in that deeper scene. It wouldn't surprise me tbh. Dupree was already outed as an abuser years ago and no longer works in mainstream porn since 2020 I think. Also, apparently Vixen despite dressing itself as this fancy porn company still has a lot of troubles and shady stuff inside like almost all other porn producers. The guy who was Mia's agent at the time and his company (motley models) also recently got exposed as a creep and doing shady stuff. So yeah, part of her retirement is probably because mainstream porn is too much for a girl like her. She also keeps a very low profile despite still doing the occasional video for her site.
