No, you see, honey, I'm not confusing anything. The thing is, it's hard to define what a spoiler is in this globalized world we live in, so in general terms, we define a spoiler as something (especially something revealing of plot or character development) that hasn't aired in either an episode or a promo in the United States. That doesn't mean that people all over the world won't be spoiled if they come here and read the discussions, but this is a mainly US-based site. I know, I know, not fair, yadda yadda yadda, just remember I myself don't live in the States either, so...
Now that's where something crucial lies:
consideration for the other posters. If something is treated as a spoiler and someone doesn't want to know, they won't be unpleasantly surprised by reading it by accident. Now, if someone
wants to be spoiled, all they need to do is highlight it and read. No harm done to anyone.

I say the consideration for others is the key because of the example below:
Let's say "The Sixth Sense" premiered two weeks before at your local theater. ( So it means that it's not a "new" movie anymore, in the sense that people had already seen it.) You are standing in line to get in and the people from the previous show are just leaving. All of a sudden you hear, "Damn, I never ever would have guessed that Bruce Willis's character was dead all along!"There goes your fun. Let's face it, you will still enjoy the movie, but 99% of the genius of that is that you
don't know that he is indeed dead. So, someone mentioning that is not breaking any "rules" as spoilers go, but they, well,
spoiled the fun for almost everyone.
I'm saying this because I myself ruined the first season of LOST for a dear dear friend of mine. I knew it as soon as Ian was told he was going to be killed off. I was so pissed that I went, "I just heard that Boone is the character getting killed off!" My friend just went, "Hmm, erm, and now the whole season is kinda ruined for me..."
So, all I'm asking is that people be considerate of other posters. I understand that a fan, who understandably scours the net for info, would be
dying to tell what they found. But there are people who just might not want to know. And we have to respect that.

My advice is... if you are in doubt, treat it as a spoiler. This way, if people want to know, they can. If they don't want to know, they won't be spoiled against their will.
Thanks for everyone's collaboration on this.
