I've a tendency when I write fic, which admittedly seems a long time ago now, not to give anything much away in the preamble at all. I sort of think ... well, novels don't, and plays don't, and films only do to an extent.

TV series do most of all: you know if it's before the watershed there are things you will not see, and no matter how hard you try to avoid spoilers you generally know if a major character is going to die because casting spoilers are the hardest of all to avoid. And films the same.

Plays don't. Novels don't. I don't want to. It's like being supposed to use a film board's censor warnings for fanfic.

I don't know what might or might not be triggery, and my preference is to go 'Here's a story with these people in' and that's about it.

Yes.
