ProductHunt is very gamified. You have to jump through their hoops to do well, reach out to "hunters" (these guys will put this badge on their twitter/linkedin) to post for you to get the boost from their following, schedule to launch at the perfect time, spam people to upvote you. People buy bots, PH doesn't care like HN does about voting rings or authenticity.

We launched D2 to 629 upvotes on HN (https://news.ycombinator.com/item?id=33704254), and 1.3k on Reddit. I didn't want to fuck with all that ProductHunt checklist stuff and threw it on there and got 9 (https://www.producthunt.com/products/d2).

In hindsight it was probably worth playing their game. It does get a lot of traffic. I just never visit the page because I know how gamified it is.
