Happens with a lot of posts, if they don't reach a critical mass of upvotes early on. In this case probably nobody could verify, if the claims were correct.

There is a new feature on HN these days to fix this: If a post get upvotes later, it will often be given a second chance to ‘try to shine’ to the front page.

With this comment I think it was to hard for people to understand in the first place.

It's not if a post gets upvotes later, but rather if a moderator or a small number of story reviewers notice that it was a good post that didn't get attention. We've been doing it for quite a while now https://news.ycombinator.com/item?id=11662380. The long term plan is still to open this up to all users, not just a few, but we still haven't figured out a good way to do that.

Maybe we should add a new topline category, "threat reports"?

I actually like that option, it would allow us to filter and extract the info as well. I could see a nice little app on my phone where i could setup alerts based on the systems / apps i choose, and getting a notification if one of them where tagged. A little bit like Have I been pawned, but with software and hardware threats.

This seems outside of HN remit, but definitely worth being a site of its own with an RSS feed. I feel this should be curated not based on community voting.

US-CERT is already a thing. But we all hang out here. I think this community has a special collection of talents that could foster positive relationships with the larger society.

I've found that sometimes a "why was this downvoted" response to an irrationally downvoted question can turn it from grayed out to black again.

Herd mentality for sure.
