I think that's part of what makes the issue complicated; everyone has a different idea of what a spoiler is and how they should be handled.

After a bad experience with a show ending badly and destroying the fandom, I want spoilers now and often won't even start watching a show until after it's over and I know how it ends. I'm done with surprises. I try to be considerate of others, though. I probably won't use that icon for at least another six months, maybe a year.
