She hasnt read the rules of Punt Club
Rule 1 - respect privacy and be discreet - how can you do this with bank payments showing your name!!!
There is no reason she, or any other SP, can't do this.
"We" can choose to comply or not.
The issue here is that she doesn't mention it in her advert ... and then agreed to a booking BEFORE she revealed it was a condition of meeting her.
I think a Neutral is generous and a Negative is more appropriate.
