Scam aside i wonder how well these high end matchmaking ones work for ones that are legit versus ceos hiring rental girlfriends/trophy wives as opposed to real relationships but i guess depending on a reputation, might be better to have an appearance of marriage as opposed to a playboy depending on the job/culture (if not the women expected to still be somewhat decent at working and not some average graduate not starting job hunting yet [or maybe this 'shady' version just has rich ppl bidding versus everyone being scammers and not that rich])
Depends
Far i know, this kind of "irl tinder" don't happen so much more in irl because of the scammers. Japaneses still have those arranged dates and if the person don't wanna rely in this kind of thing, they the high end party of this kind of thing.
Rental girlfriend dont exist in my country( i guess is a asian thing) so i can say anything about it.
Prostituition depends of country. In country wich this kind job isn't illegal you will have sites and places and even apps to find a girl or a guy wich suit your "taste". in country wich this kind of thing is illegal they have """hidden places""" and the streets.
Sugar danting have apps, sites and a really heavy filter.
