Bumble fumble: Dude divines conclusive location of online dating app consumers despite disguised distances.

And it’s a sequel to the Tinder stalking drawback

Until this season, dating app Bumble inadvertently offered ways to get the specific venue of their websites lonely-hearts, a great deal in the same way one could geo-locate Tinder customers in 2014.
