I actually don't care about "spoilers" in a story... unless it is a mystery story specifically. Telling me who done it from the beginning ruins its purpose.
RPG storylines though? I don't spoil the experience I'm after by learning every little nuance of them before i play. When I begin playing an RPG, it is the immersion I am after... and knowing a story better only immerses me all the more within it.
That being said, a lot of people love to play games to experience new things. I tend to spend more time reading about my games than I do playing them. I respect these people a lot, so I will denote spoilers when I deem it appropriate. Kind of wish I had spoiler-level commands (Green hide tag for things that shouldn't spoil it for anyone, yellow for those 'maybe it will' variety, and red for those epic endgame spoilers that can ruin entire games for people)

Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
