Because years ago I had an ex whom whenever I was at her parents, they would snoop through my phone. I'd seen a joke image of a large colored box with that text in really tiny letters(so you had to squint to see it) and decided to copy it on my phone lock screen. Needless to say, they stopped soon after. But I kept it around ever since because I think it's funny. I just set the "emergency lock screen info" to that text to display it.
