...you see that he has provided his handle and reviews?
I have no doubt that what you are saying happens. I won't argue that point. My point is you have made this very general about anyone that offers up his handle and reviews during what you make me believe to be first contact. Maybe you just didn't go into details to save time or didn't think it was necessary to make your point. (as I said, I'm sure this does happen) But the very broad brush you used to paint all guys that give you that information is unwarranted and unfair.
I may be wrong but it sounds like you use the term hobbyist as a separate category from other guys that see escorts. It sounds like you don't have a high opinion of "hobbyists". I won't assume that so I'm asking.
