Sometimes. I spoil things for myself sometimes as well, like before the first time I watched Notting Hill, I looked it up on Wikipedia, and I accidentally read the entire plot summary (as in, I started reading it and had read the entire thing before I thought, "Damn, I think I just spoiled the movie by reading everything that happens"). LOL. I don't really mind as much as other people seem to, though, so it's not really "spoiled", just "not as surprising as it would otherwise have been".
I don't get why awards ceremonies can be "spoiled", though, it's just information . With things like that, I really couldn't care less if I see it or not as long as I actually know what happens (if I actually care what happens, which I often don't).
