So I’ve stopped paying too much attention if a product claims they made it to #1 product of the day/week/month on ProductHunt.

I think the problem is that they don't seem to have a good enforcement mechanism, and so for what must've been years I haven't really seen staff proactively go after those who do game the system. The only times when I've seen action taken is when the community comes out and basically calls out a product/maker. Most people don't care enough to do that kind of stuff, I'd imagine. I've done it a few times (either outright illegal stuff like peddling American legal services from overseas without qualifications, or obviously scam crypto projects) but these should have been obvious. The staff is also unresponsive on email, although better on the forums.
Almost every PH post these days has a little back and forth comment thread between the maker and the people who they've clearly asked to upvote and/or comment.
