FWIW, a couple of her reviewers have 20+ posts, another has almost 20, and another has 4 reviews.  

Why don't you PM a couple of them if you're hesitant?

But I must admit, I think you're going a little overboard. Jessica has 8 fantastic reviews (all 9's if I recall correctly), 3 of her reviews are written by reviewers with 20 or more reviews. Her rate is very reasonable, and the fact that her reviews are all recent makes for even a stronger case to go see her. Why don't you pm one of the reviewers to ask them anything the juicy details didn't explain or divulge. If I didn't live way over on the east side, I would have seen her by now. If you decide to see Jessica please write a review. Good luck

I'm just a little concerned, simply because I saw this link on backpage, for a girl who was a part of the big sting, and the same user apparently put up Jessica's ads.  Is this too much coincidence?

Caution is great.  But if you are too nervous to trust 8 great reviews by some experienced reviewers ... why are you subscribing to this resource???
