It's not really a grey area as far as the Games of Thrones topic is concerned, people are discussing the show rather than the books and a lot of people won't have read the books, ergo they are spoilers, sometimes massive ones. They're essentially separate.
Well, I'm talking about things like, for example, talking about certain characters having their name changed, or how their personality is slightly different from the book version, or that such-and-such a scene wasn't in the book, or whatever. None of that is plot-related or particularly spoiler-ey, but it still rankles some people (so I try to avoid it).
What it is, I guess, is information that non-book-readers won't get anything out of. So I guess it's not spoiling, but annoying in a different way. Like having several people in a thread talking about something irrelevant, in a language that you don't understand.
So uh, yeah, I see your point and agree. I think. I'd wager that Game of Thrones spoilers have been discussed to death, though, so I'll just leave it there!
