Even without looking at these ads, I could tell you it's a scam. Even the scammer know that, preying on your hopes that there are women like this available.
Kamloops is inherently a pretty dry place when it comes to providers, like only two handfuls of legit providers; while one hand are locals (which in of itself could be a scam, or worse), and the other hand are travelers passing through, and getting booked up quick once they advertise.
Best bet, save your pennies for a big trip to the city.
