This post is not a Harry Potter spoiler
But I have now read Harry Potter spoilers that discuss whether Harry lives or dies — unexpectedly popped up in my feed readers — and that’s ok, because I’ve read equal numbers of each spoiler. My current assumption is that one was leaked, and JKR/publishers leaked the other deliberately to foil the first leaker (I assume they’d've done this whether the correct or incorrect spoiler was leaked), though “people make shit up and claim they have inside knowledge” is also a likely answer.
