so lets say i were to just take every ad on backpage throw it in a virtual hat and just pull a name out of their and go to that provider. what r my chances of being part of a le sting or any other bad situation that were to arise.

and there are no "odds" for your question.  The simple reality is that EVERY time you consider visiting an unreviewed lady who doesn't screen you run the risk of walking in to a sting. The same holds true for rip-off, bait and switch or just plain bad service.

No one has compiled statistics but I can tell you that, as a guy who spent years using Craig's List and picking up street walkers, my satisfaction level went way up when I started limiting myself to TER reviewed indie and agency ladies.

co-sign Bostonguy57 and you'd have better luck no matter what site the lady is posting on if she has some reviews.

Biggest odds are it's spam, by far.

Next is a rip-off of some variety

LE & honest ad probably both are much smaller odds.

Yeah. These numbers are purely guessing, but probably not THAT far off.

50% B&S
35% Total RO
10% OK provider (below 7)
5% Good provider (7 or above)
1% LE

They seem way off to me and if it's BS it might as well be a ripoff...it's like giving the same thing 2 diff names.
