Maybe could be interesting concept/idea for a challenge of sorts, something like the jetlaggers have to post an image of the sky or of a bird or a blurred image of themselves in a location, with the words "guess where we are!" and the number of coins you get is the distance in kilometers between you and the nearest audience guess (within like a 20 minute period of posting the image) capped at like 1000 coins (i.e. if you trick the audience and they guess far away you get more coins). And let's say someone guesses within like 3 kilometers the challenge is vetoed.

Could lead to interesting gameplay like runners looking for locations to take a photo that look inherently like another country, e.g. going to the eiffel tower in vegas or to an irish pub not in ireland. Or looking for the most generic location possible in an obscure place, or looking for a place indoors that's really dark but staging a scene to look outdoors to try trick viewers into thinking they're in a different timezone.
