Rejection is not the university the same. I've been rejected by escorts on Grindr and scruff but how they reject you also matters. Years ago when I had a 31" waist and 21" biceps NickFit, or whatever name he's using now, contacted me and asked for a bunch of photos and he seemed really into it. But right before we were about to meet he blocked me. Some may say this was a catfish/pic collector but he was working as an assistant manager at a local store. I even went to confirm and he was there. I'll never hire him.
My point here is, if an escort says something to the effect of, hey sorry you're not my type but I do offer massage services..., is very different than leading someone on and then just blocking them without explanation. A lot of this goes back to simple manners and courtesy.
