Wouldn't you be intimidated/spooked if someone showed you pictures of your spouse walking around? An outright threat in words would be stupid, unsubtle, and reportable; mere suggestions let the thugs get away with things. Although pictures probably already cross the line... I remember seeing a female friend in a park, she was apparently on a walk-around-town date with some guy from Tinder. I didn't want to interrupt so I didn't approach them. Then I thought it would be a funny prank to follow them around the city and take pictures, and send them to her later. And then I realized, WTF, no, it would be creepy...
