AW could solve this so easily - stop allowing girls to change their age, nationality etc once the profile is set up. Except maybe Benjamin button of course. Nationality should come from passport, as well as age and dob.
I’m sure they make money hand over fist (pun intended), but little has changed in so long. So many tiny additions would really add value to both providers and punters - different service lists for video chat/meets, did they used to offer a service, etc
