Comments by new accounts posting from Tor IPs get autokilled because of past abuses by trolls. We restore the legit ones when we see them (or users tell us about them), and mark the accounts legit so future comments won't be killed. That's what I've done here.

It is more of an "under moderation" thing than a "dead" thing. It's on our list to make that explicit and to provide a mechanism for the community to make most of the moderation decisions.
