Just a new user thing probably. It’s been resurrected.

I had to click "vouch", because the comment was dead :/

Sometimes new accounts get (mistakenly) caught in anti-abuse filters. If it was [dead], that’s likely what happened. If it was [flagged][dead], it was the result of user action. In those cases, vouch as you did. You can also email the mods using the Contact link in the footer to make them aware so they can take a look at what’s going on.

You're being targeted. This comment was dead too. :(

"Dead" indicates an account-level filter, not flags applied to a specific comment.

Often this is based on prior history, based on exchanges with admins. It's possible for accounts/users to be rehabilitated. "Vouch" actions or emailing mods can have effects.

Sad thAt this kind of immature behaviour is on HN. Mods should be easily able to search for this kind of behaviour

How nice to be downvoted for this comment.
