(I also reposted the comment above btw https://news.ycombinator.com/item?id=24090447)

Dead comments can be resurrected by people vouching for them. If you think a comment from a banned account is something that should be shown, click on its timestamp and then click "vouch". I usually look at the user's other comments first, to see who I'm vouching for.

Do you have showdead set to "on" in your profile?
