I usually google their numbers and find as much as reviews as possible. Then I also look at profiles of reviewers to make sure they’re not fake. For those with no reviews, I do imagesearch on their pics. If pics look too good to be true, I back off. If pics are very low quality, I assume they just copied and pasted those pics from random social media. I noticed a lot of escorts here dont post their face pics, I think that’s a good indication of Provider being real.
