Ok valid point.
I think when it comes down to it there are profiles where the girl(or possibly it's a guy who has set it up) will log in daily, supply private pics and fake pics, have zero reviews and not respond to booking/email requests and don't have phone numbers on the page. On top of that the girls have zero reviews on sites like this, of which there are a few. The point of advertising as escorts is to earn money by shagging guys yet they do fuck all shagging. Will there be direct irrefutable proof, most likely not, but the experienced punter will spot these profiles a mile away and the more that get outed the better to view genuine profiles.
In scotland punting is absolutely shite at the moment and it's not helped by 10's upon 10's of profiles of girls(or guys) trying to shaft punters looking for a good time.
Case in point I'm aware of 2 girls I know personally that actively do this, they have zero intention of punting yet advertise themselves as hookers so guys will check out their private gallery thus scamming them out of money. I actually know of a bloke that done this a while back too!
