Do you have 'showdead' configured?

It might be auto-flagged. Some domains are. dev.to is one of them--I have seen some great posts there but don't share any here because they are all auto-killed.

Have you read the FAQ: https://news.ycombinator.com/newsfaq.html

That might answer some of your questions.

After a quick glance at your submissions, you seem to be submitting things mostly to promote your own projects or your own writings. Posting things primarily to generate traffic to them generally isn't accepted here.

The "AI Guide" looks to have been automatically marked as dead, probably because so many of your earlier posts were flagged to death. I vouched to revive it because it seems like it might be of interest, but it's still another self-submission.

Overall, I don't know. It's on the edge. My guess would be that HN might not be a great fit if your goal is primarily self-promotion. You might email 'hn@ycombinator.com' and ask for their opinion.

I don't know.

To the degree it is important, I suggest you contact the moderators.
