Yep, this post is now showing as flagged and I have no option to vouch for it. Not that I would in this case, but the option is not there for me.

Users can flag submissions. There isn't a vouch option for submissions, but upvoting acts a bit like a vouch.

Users can flag and vouch comments.

If you think a story or comment is unfairly flag-killed you can email the mods I guess. This is particularly useful when something is being talked about on HN and the author / creator makes an account to join in that conversation. They'll sometimes find their account is rate-limited because it's a new account.

I definitely have a “vouch” option for submissions. I think it’s a newer addition than vouching comments.

Thanks, that kind of makes sense.
