Fictional Fans

Hmm, I get your concern there. In that case I'd go by what the fandom norm for it seems to be--if fandom mostly doesn't care about spoilers and MUST have them, then it's not something you might want to enforce. I'm drawing on memories of when TRC and xxxHolic were coming out, and it's true that fans often don't care about spoilers, but I think they were put behind a cut out of courtesy.

Maybe once your comm has enough people, if you're still unsure, you could take a poll? Then it would be more of what the community wants, rather than you second-guessing. Having an outline of what you'd do with it in place until then might work.

And you're welcome!
