I would need the see a decent picture of her face before booking, and I have considered this lady and exchanged email with her in the past. It could go either way though. She looks like she has a decent body so, if the tats don't bother you, she could be a smoking hot milf. Conversely, if the face ain't up to it, I'd be running for the hills.
In this case, and in the absence of a fair quantity of anecdotal evidence to the contrary, I assumed the latter and politely moved along. Maybe I got it wrong, maybe I missed out on a great experience. But maybe I saved myself.
I understand why some ladies require anonymity, but a white circle or a blur over a face picture is not going to achieve that when there are clearly other identifying features on show (the sleeve tat for starters). In which case why blank the face?
It's a bit like going to look at a car you are interested in buying only to be told you can't see the front end until you have handed over your hard earned.
A crazy and frustrating situation, I'd almost prefer that ladies go to more lengths to hide themselves in photos. Then you at least know they are after discretion (a value most punters rate very highly) and not just trying to hide a face that looks like a bag of smashed crabs.
