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.
