Is there any official policy for mandatory use of the spoilers features? 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?
If there should be such a policy, should it have a statute of limitations? I'm pretty sure we all know who Luke's father is...
Also, for examples like this, I understand that there might not be much left if you blotted out all the spoilers. Should posts like that be handled any differently?
I have looked at this question but I feel it was not fully answered by the question it supposedly duped. The original question mentions how the spoiler block and spoiler tag work, but does not mention how posts should be handled that contain unmasked spoilers.
Also see this network-wide question I posted on MSO before coming here.
