I have been with Kurtis, and found the encounter very enjoyable. He was very friendly, engaging, smart, and we had a pleasant conversation after. I understand his frustrations when there are so many 'proofs' that he is real in his ad sites, and then you get a pic collector who asks for more or simply gets off on the back and forth encounter with him on the guise of a possible set up.
I personally believed his ad and set up was seamless, and I had an awesome time with him. That being said, I have seen accounts on RM where pictures were duplicated by impostors. I, ask for verification myself when I see pictures of guys "to good to be true" with no other links to back them up.
So this may be a case where we shouldn't generalize that asking for verification as a wrong thing, but we should also be mindful when it is already inappropriate and frustrating from an escort's point of view.
