Aliens don’t read random threads (’cept perhaps JRandomFreeper threads). Aliens are verrrrryyy sophisticated and use very sophisticated algorerhythms to decide which threads to read and which to ignore. But you can be sure that aliens read the entire thread once they decide to read any thread. It’s just the way aliens are. Sorta natural law-like, I think.
As long as they don’t inspect the condition of my lower digestive tract, I’m good with that.
