I created a small script that detects users coming from Product Hunt and blocks them + redirect them back to PH.
Product Hunt became a huge part of a product launch and at getting traction. But it can be ruined by a premature hunt.
I hope this tool will help some people or maybe start a discussion at PH to address this problem for all product developers.
The snippet is available on github as well if you'd like implement it yourself: https://github.com/marcantoine/donthuntme
