Nah, i'm a big fan of mistery series and discovering unknown stuff. Spoilers definitely dampen the enjoyment of stuff like that.
But i also know that not seeing spoilers is primarily my own responsibility. I don't go read discussions of something i don't want to be spoiled off for example. Or watch trailers of it.
I can (and sometimes do) these things after the fact if i don't have the time to consume said entertainment at release.
Especially on places like GAF people are courteous about spoilers, I've never been spoiled unless i deliberately went into threads about the game itself. And that's on me, and i don't accuse poster 154 of being a dick because i saw a spoiler.
