Can we add posts with negative karma to a Sequence? I'm working on a Sequence for my alignment research agenda, and the most valuable content in the sequence is all currently underwater. I get that LessWrong wants the community to have veto authority over people creating Sequences and adding controversial posts to them, but I am not sure how to proceed with my alignment work in the absence of a quorum of people willing to upvote the most valuable and important parts of my research agenda.
For search pricing reasons we don't show downvoted content in search results, though the intent is definitely not to make this kind of thing impossible. It's just a result of me trying to come up with some ways to reduce the number of things in our search engine so we get charged less money for that (we now moved to a different search provider which also makes this less relevant, but it would require some code changes to make them visible, and I would still want to make sure downvoted content only shows as a last resort)
