You can look for reviews from other sources. If you get a membership on a service like Date-check, and if she's listed there, you can see where else she may be reviewed.

You can't tell if she's any good by her ad, pictures, or the sound of her voices.

Unless she has reviews somewhere else that you can access.  Many providers do not want reviews, so you have to rely on backchanneling with guys that have seen her, and that might prove to be very not worth it.

If I can't find reviews somewhere, she is not on my list of ladies to see.  I'm not gonna TOFTT just because she looks hot if I can't find out anything about her on some site, whether here or somewhere else.
