in the feeds we use the spoiler tag to hide all sorts of stuff, not just spoilers. not drama related posts, posts that might be of a sensitive nature and sometimes even just posts that are going to be super long. once you've marked your post as a spoiler the only way you can let people know why it's hidden is in a comment, which might get lost under all the other comments on a post.
what i am suggesting is that, either, 1. we are able to type above a spoiler tag so we can explain why the post is hidden or that in addition to a spoiler tag in the feeds we have tags like "not drama related/off topic" , "mature content", "long post"
