I hate to belabor the point, and I'm pretty sure you get it anyway, but it's not the general subject or tone of the story that matters, it's the exact wording, which would be very hard to guess, especially for longer excerpts. It's not a matter of finding a "story" that's hard to guess, it's a matter of finding exact wording. I'll guess there's going to be some kind of trouble with the space shuttle next week, but that doesn't help defeat rsync.net's scheme.
