There’s no “we” have to protect ourselves, it YOU who made the choice to see a lady with no reviews, it’s YOU who chose to go ahead with the appointment, even though you were dissatisfied with her you still handed over money and took her service, I bet you were planning your bad review for her all the time. Not nice.
You try asking any quality escort to prove themselves by WhatsApp and you’ll be laughed out of it before being blocked.
I’m sorry but I find it pathetic your moaning about this, it was all entirely your own fault and this “calling to arms” of fellow punters to demand this that and the other is hilarious, I can’t imagine how someone like you survives in day to day life at all.
