I've not seen anything that creepy, but one of the youtube channels I watch is an outdoors person, and she posts videos of like building shelters and shit, along with other things but honestly those are the ones I care about...

She posted a thing awhile back after taking some time off, apparently one of the viewers recognized something in one of her videos, and decided to spend weeks wandering around forests trying to find her.

A dude literally went out of his way for WEEKS to find a woman he has never met, who doesn't know he exists, and he knows travels alone in the woods, so he can be face to face with her in the middle of nowhere..... And didn't see a problem with that apparently.

Now in this instance, it was more of "wander a large area looking for signs" but another YouTube (tom Scott) posted a video awhile back giving as little information as possible, and it was him standing in a cornfield. Only a small bit of the sky was visible. He literally asked for people to track down that spot, in order to prove a point in another video.

People did it scary quick, unfortunately there was either a plane or a contrail visible, and with time of day and the sound of a nearby frog people got the spot to within a few feet or something like that. Details are fuzzy, it's been years since I saw the video.
