So I set up an appointment with a girl whose ad I saw on BP. She has about a page of reviews on here as well as on another review site. She also has a website. The only problem I'm having is that she didn't screen me at all before giving me her address, and we've just been texting back and forth. I'm feeling a little sketched about this and I am thinking about canceling the appointment? Do you guys think I have anything to worry about?

I would, safety first especially if I you are seeing someon on BP. I don't visit anyone that is solely listed on BP.  

I've had that happen, and then when I got to the location the girl had me text her a few forms of ID.  Also have met with providers who didn't screen at all and turned out fine.  If her reviews are legit then should be ok

Wouldn't worry too much.  Had a similar thing happen, no problem.  Just make sure the reviews are fairly recent, same or past month.

if she has many good reviews by reviewers who also have a good review history, she is probably fine.
