I've been skeptical of those reviews as well, along with previous ones for Riley Reid and Autumn Falls, which seem to have subsequently been removed.  They all had a similar "feel" to me, using similar terminology or focusing on similar things (the provider's teeth, for instance) and the reviewers' names were often similar (Bigbryce48, kurtis58, Guitarist38, Bignate54, Jim64 and so on) and one and done.  FWIW, however, someone on a Reddit escort thread did say that the latest review for Mia came from a reviewer with a long history, but I'm not VIP at the moment so I can't confirm.  For your sake, I hope it turns out to be true

Mia appeared in a recent pillow talk podcast , I doubt she provides, according to what she said about it

Unfortunately for me I have tried and I can confirm it's a rip-off. Posted my review on her profile. I immediately got confirmation by another TER member that it happened to him as well.
To be avoided at all cost...

Believe it or not, she’s been making close to 3 million a year on OF.  She bought some historic estate in Oregon or Washington.    

When I made the poor decision to use OF she asks major money for fans using her site.
