Just a little heads-up, your account appears to have been shadowbanned.

That post is publicly visible to me. It also seems to be the first post for the account, and is fairly substantive.

Moreover, I don't think it's even possible to reply to posts made from shadowbanned accounts.

Okay then.

I didn't look at the poster's history, I just saw a constructive-looking comment that seemed to be modded to oblivion, and jumped to conclusions.

I had to vouch for the post before HN would let me reply, which seems consistent with how shadowbanned accounts are handled here.

Sounds like someone flagged it for whatever reason and it was flag-killed.
