How Product Hunt really works

In my experience, the OP is correct about one thing, it's waste of time to post on upcoming on PH. However this is nothing compared to how opaque Hacker News is. If your product is novel enough and reach out to these "insiders" beforehand (or even afterhand), I don't think you have trouble getting to the front page on PH, whereas on HN I see tons of people reaching front page by asking for upvotes from friends. The only difference is PH is--ironically--transparent about its opaqueness, whereas HN is opaque about its transparentness. To elaborate, on hacker news everything looks transparent, and to certain degree it is (you can find the raw stream under "new" tab), but the ones that reach the front page are not always there because 100% of the community decided so, there are many hidden things going on in the background that most people don't even know. Whereas all you need to do to get featured on PH is to reach out to these "insiders", to guarantee you reach front page on HN you need to get people to upvote you. I feel that PH is much more democratic than HN since everyone gets same chance whereas on HN the people with already existing audience wins.

Asking for upvotes does not work on HN, and using shennanigans like mass voting from /newest doesn't work either. (the points register but they will not be used for ranking)

Product Hunt, in fairness, has the same do-not-ask-for-upvotes clause in their FAQ, but given the amount of people blatantly asking for upvotes on Twitter (https://twitter.com/search?q=product%20hunt%20upvote&s=typd) I am doubtful that policy is actually enforced. It's free publicity, after all.
