Furthermore, I've used it plenty of times before traveling to set it to a country where I will be going. I am very clear about not wanting a hookup and just meet up with locals and that has been working quite well.
Not everything is about having a hookup.
Maybe long distance is not your thing. Some people have bigger intentions than just fucking on a first date.
1) A small number of desperate people in poor countries trying to score a way out. Marriage is one of the rare ways for unskilled people from the 3rd world to get legal residence in the 1st world
2) Tons and tons of crypto scammers. So many crypto scammers. "I'm actually in Hong Kong right now. I made tons of money investing in $ponzi, and now I'm a free agent. You should make an account too, then we can travel together!"
Unless you're ready to hop on a plane and go fuck your match halfway across the world why even bother? Is it for all the people hoping to hook up when they arrive at their vacation spot?
