The Presurfer highlighted a Chilean ADT home security company that used spring loaded paper boxes to make people think there had been an intruder in their home. The paper box is slid under the door flat, and a rubber band inside expands it into shape. The only text on the box was said to have been: “Breaking into your apartment is easier than you think.” Well done. Creepy, but well done.

What’s your take? Does this door-to-door marketing strategy cross the line?
