I've seen the profile and to be honest I just moved along when I saw the rate. I guess I should never say never, but if I were ever to pay something like that, it would be someone very well established, with face pics, and someone who doesn't make setting up an appointment look like a lot of work.
I'm not even sure she's here. None of her reviewers saw her here, her site leaves you clueless as to when & where she's available, and what she needs from you for screening.
You're right, her reviews don't leave a warm fuzzy feeling. Not saying she is a scam or anything like that, just can't be totally confident. Her latest review, the guy says he's seen her several times and she deserves an updated review, now that he's a seasoned player. But it's his first review, and she doesn't seem to have much of a reputation. At least not an obvious one. Can't find her on 411. I didn't go searching the other reviews sites, but a quick search of her email address turned up her profile here and her indyfiles and crickets.
If I were interested in seeing her, I'd wait till she had more of a reputation to make me feel more at ease. But that's just me. In the meantime, go see Rhea again, she's a sweetheart.
