I have to agree with you Prof. A quick look at her AW reviews (all 7 of them) shows that none are for actual escorting; all Direct Cam.
There is too much of this sort of thing going on, and it has got worse in lockdown. Escorts who just tick the escort box to get you interested, but a read of their profile makes it clear that they won't escort without camming first (if at all). I suppose some might escort after a load of camming sessions if they like the look of you and/or you offer them enough money, but mostly it will just be throwing money away, unless camming is your thing of course. It's the latest equivalent of B&S.
