Ok, a link like https://news.ycombinator.com/newest?next=48799132&n=31 (the current second page) is actually stable, so let's do a a review of that.

The two submissions from bamei2ai are not working links, so no questions about them.

Most of the others are from new or very low karma accounts, ok, but is it forbidden to submit something before having gained a good karma? Are submissions from such accounts killed automatically?

The only dead post left is https://news.ycombinator.com/item?id=48798889 , I'm not sure what's wrong about it

Reported #36 site by email for possible astroturfing. Reported #48 user by email for volume. Reviewed all existing [dead] instances and they seem appropriately so for various reasons. Reported a possible antispam bug that, if I’m right, when fixed would mark two more as [dead].

There’s nothing particularly unusual about this page of /new. I opened up current /new after finishing this post and on page one found a YouTube link, which made me think “that’s odd”, looked more closely, and ended up writing a twenty minute mod email reporting several more sites for spam; the future [dead] count will increase accordingly.

> is it forbidden to submit something before having gained a good karma?

Not precisely, but it’s in really poor taste after the first time, and I believe the mods tightened up the Show HN thresholds a bit recently due oto the codeslop flood. This is a community, not a marketing channel; if they’re not here to submit and/or discuss other people’s work, then it should come as no surprise that we’re not here to discuss theirs either.

> Are submissions from such accounts killed automatically?

Not that I’ve seen. Certainly lots of them end up killed b/c spam bots are detectable, but it’s not uniform. But, as I said a couple weeks ago in a variation of this post: Either genuinely invest time and energy into this community or move on.

#51: Boring submission. Poor composition skills, no effort invested in even basic capitalization. Open admission of AI-generated writing: “The site is a bit slop”. Deserves as much attention as effort invested. This post could have been replaced by a training harness.

User has only <100 karma on an account 5,000+ days old, so this is less a site participant, more a fly-by-night forum spammer as their participation stands right now.

I would flag this if it wasn’t already flagged. Thanks to whatever HN system or user saved me having to do so.
