1- Try using hacker news to deliver value to others instead of just posting only about your own platform or links to your own domain name. A good basic minimum rule of thumb is to have 1/3rd of post only about your domain. If you don't do this, it comes across as you are using it only for advertising your own product.
2- Don't use AI generated text at all, ideally avoid even grammarly.
3- Comments on posts or creating posts only you truly understand and genuinely find interesting. Focus on helping others and genuinely delivering value instead of just just hoping for karma.
Of course, I can't promise this will help, these are my best guesses.
