I'm really curious about voting ring detection. Oftentimes I've seen posts from the same company hitting the front page over and over again, and none of them was particularly interesting, nor was the company any of HN's "love children" such as Stripe. I can't recall any specific example, but when looking a bit closer it was usually some small- to medium-sized startup with maybe 10-100 people, which would technically be enough to make a big dent into a post's score.

On the one hand I'd love to know more about the detection algorithm, on the other hand that information would be inevitably abused by those shitposters to game it.

Ring detection works for people who don't know it exists. And thus works well a lot of times. But is very easy to bypass, and I won't tell you how.

And if I recall well, dang has already said several times that he will not disclose the algorithm https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...

That really depends on how it works, and whether you know how it works. Simple signals such as IP location and temporal distribution of votes are easy to use for detection, but also easy to manipulate. On the other hand, if you employ a graph of user associations based on votes and comments in the past, you can detect clusters among them, voting collaboratively. This is way harder to circumvent in the long run, but also extremely difficult to implement accurately.
