Interesting progression. For a while, it was flagged, and still racking up points at the #1 position, but now it's gone far away.
I wish we could actually discuss the issues raised by situations like this, without the pitchfork and flagging brigades coming out. You would think a site focused on technology could discuss IT security, hacking, and the potential influence of technology companies in shaping and directing political opinion. But unfortunately it tends to get shutdown before anything can get started.
You have to click on the comment's timestamp to go to its page. Then (assuming the comment is [dead]) you'll see a 'vouch' link at the top. That's the same place where the 'flag' links for comments appear. If the comment isn't [dead], there's no 'vouch' link, because the reason to vouch for comments is to resurrect them from [dead].
> The system used to say [flagged] only when the story was both heavily flagged and dead (closed to new comments). Now it says [flagged] if the story is heavily flagged, dead or not. Flagged-but-not-dead was the case here. That's why you didn't see a 'vouch' link, btw; there's no need to vouch for posts that aren't dead, since the purpose of vouching is to unkill them.
