Considering polls are embedded in a post, if the post is within a category with permissions, the polls should take into consideration those permissions.
Beyond considering a vote a reply or not, any sort of interaction with the post should be considered in those permissions, as they are essentially part of the entity controlled by permissions. Does not makes sense to me that anyone can interact with a “View only” post because the post is fundamentally its content, and that includes polls.
I propose that polls behave the following way according to the permissions applied to the category of the post:
- See: Only see the results (partial or closed), taking into account the “Public” to show or not voters.
- Reply / See: Same as See plus the ability to vote
- Create / Reply / See: Same as Reply / See plus the ability to create posts with polls.
