For the 99% of users who open the app in a coffee shop in Ohio or a bar in Berlin, Tinder just works. But for a growing subculture of travelers, expats, and geopolitical outliers, the app is a locked gate. In countries from Pakistan to Russia, and on the campuses of conservative American colleges, the familiar flame logo is often grayed out, censored, or geo-fenced into oblivion.

But to the user, it is simply the logical conclusion of the digital age: If love is a market, humans will find a way to arbitrage the gates. You can block the app, but you can’t block the impulse to connect.
