Here are the official Product Hunt guidelines:

"Feel free to hunt your own product. Having someone else posting is fine, but spending lots of time “finding a hunter” is a distraction. You know your product better than anyone else, and it makes very little difference who hunts the product and how well it performs overall."

DON'T BELIEVE A SINGLE WORD OF IT! YOU'LL FAIL MISERABLY IF YOU HUNT YOUR OWN PRODUCT YOURSELF.

You must know that if you're not hunted by an influential hunter, then your product won't appear at the bottom of the rankings of the day as you would expect. Instead your product will automatically land in a separate listing named "newest" which is a deathtrap. Only a handful of products will have the luck to be featured and escape this dead end. The current system is a huge waste, with a majority of products failing miserably without having a single chance to succeed. PH visitors never get to see those products, and developers are kept wondering what they've done wrong. As a PH visitor, I thought that only a couple of dozen products were launched on PH each day. I was shocked to discover that it's in fact more than 100:

When a product fails, it's not necessarily because it's bad. It's more likely that it was sacrificed and didn't get any eyeball at all.
