Yeah, I don't understand what they're getting out of it. Here's my pros/cons list:
Pros:
- trust?
Cons:
- if you break up, they can screw you
- if there's a data breach, you can get screwed
- they accidentally leave their phone unlocked
- send phone for repair and the tech sees the video
- they accidentally send it to someone else, mistaking it for another
That doesn't seem very balanced to me... Instead of mutually assured destruction (assuming this is reciprocated), just be a good BF/GF? Why isn't that enough?
