Here’s an article about how Tinder fixed it: https://robertheaton.com/2018/07/09/how-tinder-keeps-your-lo...

Oh man, I forgot they originally sent the actual location. I still can’t believe how many developers think you can trust the client.

Someone even made a triangulation app to pinpoint other users of Grindr.

Aye, with Tinder, but no extra-devices or actual travel was needed: https://blog.includesecurity.com/2014/02/how-i-was-able-to-t...

Oh right, they just used the API.

Is "cutting the queue" (what this is) an unintended consequence of having a queue? It's perfectly normal behavior. Maybe it gets resolved socially, or the solution could involve tracking whether the follow-up movement happened as assumed (the real hidden assumption). Making a buffer and reducing precision doesn't solve anything actually, it makes it socially more difficult, but it's really a hack, as was choosing the closest physical phone whether a warm body was attached or not.

I think if they randomly select someone with a range, it would make it not as important to try to be physically closer. It wouldn't stop all gaming of the system, but it would be a start.

You'd want to tweak it so you were picking the person in range who went the longest without a gig rather than a naive random pick. Lot more encouraging for the workers vs watching the guy who just got a gig receive yet another before them.
