She (Sergei) states "Do not waste your time emailing me....Please try and use the phone number as the main way of communication...you might get an answer if you're genuine and serious but not the same day for sure"
Then states "My phone number will only show on the day I am working....Use the AW booking system in advance to guarantee our fun time together".
Finally concludes with "CALL ME NOW SO I CAN PLEASE YOU".
I think it is safe to say that there is going to be a slight chance she might be a hassle for people to book

You may be correct here, if there is a correlation between how the comms are written on an AW profile and what may, in fact, happen in reality
It is a good insight on your part but I think you might be being a little bit less than generous here

Admittedly the AW is not written in the best tone and tenor. In parts, it is a bit convoluted. My guess the person who wrote this profile may not be a native to these shores However, I think the point they were trying to get across was call or text but no emails and any booking will have to be first confirmed, without any such confirmation then there is no appointment.
Errr I think!!
