One time there was this scooter app that was made by a Chinese company and one of their screenshots was the scooter tracker which revealed their location so I went to Google maps and translated the city names and pinpointed the exact location of them. Weirdly, the street view imagery looks like it was taken with a frickin potato so I got to see a creepy open shack but in really low quality and I couldn't see inside cuz it was dark.

And no, there wasn't any app developer groups nearby, but a lot of technical institutes.

They have sinced realized and removed the photo and redid all the screenshots in English
