If you are genuinely sorry and want to (possibly) turn this around, here are some ideas:

1. Consolidate your work into one solid well documented Github repo, including a small toy model that people can actually use and play with.

2. Write a blog post or tutorial about your tech. That'll show your expertise without making people feel like they are being duped.

3. Engage in relevant communities genuinely. Build relationships, not just a user base.

4. Use proper channels for promotion... Show HN exists for a reason.

Remember, reputation is currency in this industry. It's hard to earn and easy to lose. Take the long view, build something good, be transparent, and let organic interest do its thing...

If your product is actually solid, there are ways to get it out there. It might be slower, but it's at least sustainable. Good luck.
