I think OP is having an unreasonable overreaction. Sure, it's nice for people try to avoid it for you. Fair enough. But it certainly isn't their obligation and it doesn't warrant the anger. This is a pinball-specific forum, meaning it's not hard for you to avoid it if it's important to you to be unspoiled, and, indeed, the burden to do so is on you.
I couldn't watch the finals yesterday and had the wherewithal not to come to pinside until I'd seen the video, for the same reason I don't visit the espn homepage if I don't want to know the results of the game and I don't visit the Breaking Bad forum if I'm behind. It's a hobby-specific site and you are acting like you accidentally stumbled over the news when you were trying to search ebay or something. That's not what happened, here, and you may want to simmer down.
