Is there any official policy for mandatory use of the spoilers feature on fiction or literature sites, like https://scifi.stackexchange.com/, or is just a courtesy/fully voluntary?
I didn't see anything on the FAQ.
Is there any particular action that should be taken on posts that do not contain spoiler blocks?
Also, for example What's with the duck pond? I understand that there might not be much left if you blotted out all the spoilers.
Should posts like that be handled any differently?
