Wonder if it's because the majority of Passport Bros are American and they're not very liked globally currently
There is no change in actual data, it is just these dumb shit YouTubers creating a story, then as a result of the publicity, everyone involved realizes they should have never publicized what they were doing.
Wealthy Americans have been getting sex in third world countries for a long time. After Covid and Digital Nomads, the people moving abroad had younger average than usual. They did Look At Me Reddit communities and Youtube interviews when contacted. Many American women gave them the term Losers Back Home, which tended to quiet the entire community.
Older expats and retirees would have known to Shut The Fuck up about this stuff from the beginning.
Of course these YouTubers think if there is a decline in Reddit posts and their interview requests have declined, the scene has disappeared. If you bring money to the Third World, and seek out women, you will get laid for a reasonable price. As to why anyone wanted to create a community such as Passport Bros and scream about it from the rooftops on Reddit and YouTube is beyond me.
