What are the best practices for using LinkedIn to drive PH traffic without being annoying & spammy?

I am trying to make Call to action a bit softer and combine with a joke Like on the post with PH launch announcement I made a banner with my cat cosplaying PH logo Then I plan to add links and branding around launch on website and LinkedIn group but use it less in content

I try to be honest and candid. We need the support, we appreciate the sharing and spreading of the word and how it'll help us to grow. Be genuine and no one can fault you for trying to work on you passion.

Definitely really great storytelling in your posts -- I'd also look at ways to automate outbound LinkedIn connections/messages to reach out to other ProductHunt-type business owners who would likely support you, then eventually pivot to your ideal customers.
