(CW: Transformation) (Note: User is always swapped with a woman.) "Tired of your boring old life? Just Switch It Up! Press that big red button, and you'll swap lives with another random user! The first swap is free!" This app seems shady, especially since it just appeared on your phone one day out of nowhere. But... Surely there's no danger here, is there? You didn't have to give it any special permissions, after all... Surely it can't mean swapping lives literally...

(Update: Tried different phrasing to get the bot to not try to swap you back on its own.)
