It's a spoiler until it's been broadcast on TV. Episode 7 is presently included in that. Once it's been shown on Sunday night, go crazy. The content of the books, of course, will always be spoilers in this thread.
Speaking of Episode 7, god damn son. God damn. be ker-azy yo. The show had a really slow start and I wasn't really sure I was going to like it other than Boromir, swords and titties, but I'm now sucked in.
