It has a [dead] comment that says
> Please don't post unsubstantive comments to HN. [link to guidelines]
My guess is it was a parody/impersonator account.
You can enable "showdead" in your profile to see [dead] comments ans posts. Most of them are crap, but there are some false positives an errors from time to time.
I like to leave dead comments on. It helps me feel better about living in a cultural wasteland to see that people who probably live near urban centers can be just as dumb! It really does help me worry less.

HN silently black holes any comment made through a VPN, so I would expect a decent amount of false positives.
