If you don't get a response that doesn't mean you violated the rules of the community, it just means you didn't get a response.

There's a much bigger question of how to promote something effectively. Unfortunately a lot of people are seduced by something like "get into TechCrunch" or "get to the top of Product Hunt" or "Tik Tok will make me a star without me doing anything."

The short of it is that marketing takes 100x the effort that you think it would, especially if you don't want to spend a lot on paid media, but it takes a lot of effort even if you do. Unless you're exceptionally lucky the first 10 things you try will disappoint you, that's how it is.
