When the apps also show the distance down to feet, you can triangulate their exact potion by moving your phone’s gps location.
Always choose the “don’t show” option. It’s not perfect, but it makes triangulation more difficult.
Also, pro tip, always ask new people to show their face while doing something that people don’t normally do, like holding up three fingers or a scrap of paper with text YOU chose.
Obviously AI makes things more difficult, but this weeds out most of the “average” catfishers.
