Ask HN: How promote your project?

Recently, I've been posting a lot about my open source project, but I was quickly told that on HN Duplicates or reposts of posts are not accepted, but please tell me what to do to promote the project, I have already tried the services: Reddit, Twitter, Lobster.rs, Dev.to, Github Discussion etc. But I didn't succeed in them HN gave me hope and I started to succeed, but as I said, the community doesn't like my actions, and therefore I can't continue to do it.

Please tell me what to do?
