> We will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, “I’ll know it when I see it”. And we think that you will also know it when you cross it.

The proper quote, from Justice Potter Stevens, was:

> I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that.

How do I know? Because by wild coincidence, I quote it on the first page of a free book I wrote (http://cs.gmu.edu/~sean/book/metaheuristics/).
