Tagging a post/comment as "spoiler" acts in the same way as marking it "NSFW" - hides the entire text until the user chooses to accept reading it by clicking/tapping on the warning.
Most useful for discussing media-related things - movies, TV shows, etc - where other people may not be caught up or current yet.
