@jdp23 I am no expert but I think that since "noindex" is the operative technical piece here, since it applies to the entire page and not individual pieces of content, would mean that if the original poster has noindex turned off, then a search engine would index all public (but unlisted) replies. As long as you can *see* the content on a page that lacks noindex, the search engine will scoop it up with everything else
