I had a look at her content and wasn't really impressed. Plus, she lists a fair few niche things, and at her age, I call bullshit. 
She gives me the vibe of someone moving across to AW from Seeking.
I think that this is the correct assessment. I wrote to her a couple of weeks ago on AW. Confirmed timing and services, etc, comms were very prompt. Then she suggested moving to WhatsApp, which I declined. After that, she stopped responding, which sent my spider senses tingling. Being in my late 30's, I am not old enough to want a sugar baby and I am busy enough that the last thing I am interested in doing is spending my time yapping away with a 20-something-year old. I'd rather just stick to the basics. I messaged her again the day before the agreed meet to confirm and stating that I would book the hotel and she responded in the affirmative. But, my gut felt the contrary, so I did not make the booking. Then, she responded later in the evening saying that something had come up and asked to rearrange.
All good at the end of the day. For what it's worth, I think that she is real and from early comms I'd venture a guess that she may actually be a great fuck. But, she is young and inexperienced and, as pointed out in your post, probably new to escorting vs looking for a sugar daddy. To be fair to her, my AW account has very little feedback (but it is all positive), and she does state on her profile that after initial comms we should switch to WhatsApp/Telegram. So, perhaps she simply did not feel comfortable to meet me without additional feedback - which is fine. Also, I ended up having an unexpectedly large night out the day before the agreed meet so, frankly, I was happy to spend the day snoozing in my office chair instead. In any event, her rates are probably at the upper range of what I would be willing to fork out and, at the end of the day, I am looking for a fuck, not a fucking headache.
