When I've done something like this in the past, most of the responses I get are shrugs and, "I guess I'll change that password, do you have any tips on good passwords?"

A few people will go off with their lighthearted hyperbole "I'm moving to a cabin in the woods!" To which I respond, it's much easier to track a n=1 with a unique heat signature in the middle of nowhere - should someone be so inclined.
