I heard about this threatened lawsuit on Westeros earlier today, but following the linked Twitter feed of "Luckers," I have to say this airing of dirty laundry is one of the strangest I've seen. I may disagree with Sanderson's approach and I may dislike his writing style, but this was a bit much...and by that, I mean the harassment of the writer by the fan, especially a beta reader. No wonder the talk of an "unseen world" exposé was silenced with the threat of a lawsuit.
