Even if they don't hit front page, the comment itself adds to the longer term plan of these accounts. I don't doubt for a second that someone has, or is currently manipulating a lot of the traffic and comments for certain posts.
This is easily established via networks of rotating residentials; or better yet, real humans in Ukraine [1]: something that cannot be defeated unless you start nodal map chaining.
High likelihood that these troll farm/serious commenters algos are not equipped to deal with such complexities such as human satire yet, which is a reasonable conclusion as to why there are so many "serious" posts

People try every day to plant stuff on HN's front page, and every day our anti-abuse systems catch such efforts and apply different types of counter-action depending on the case. I'm not saying no one gets away with it (obviously we can't know that) but I can say for sure that anyone getting away with it would have to be way smarter than that group.
In case anyone's interested, it happens that I've been working for the last few weeks on a new type of anti-abuse system, which is designed to more tightly enforce this site guideline: "Please don't use HN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity.".
That's not evidence of what you claimed upthread; it was an inept bunch of content marketers who were easily caught by HN's anti-abuse systems. The thread you're linking to contains over 20 comments that I posted explaining various aspects of this. And if you read Troy's original report you'll notice that the examples he shows of them succeeding come from other places than HN:
It's not that it never happens for real, of course. Both things happen: real manipulation and imaginary accusations of manipulation. Both are bad, and we need some sort of evidence or data or $objective-thing to look at in order to have a hope of distinguishing the one from the other. We put a ton of effort into protecting HN from manipulation and have many years of experience with this. I can't say we're not being pwned but we certainly catch many attempts to game the system here.
There's plenty of past explanation here if anyone wants more: https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...
Answer to "does this count as breaking that rule?": no, Troy emailed us long in advance and he had lots of specific data that we could look at.
Answer to "does this count as evidence that HN is overrun by bots?": no, our systems had caught most of that activity long before. I posted over 20 comments in the thread you link to, covering a lot of these points; see e.g. https://news.ycombinator.com/item?id=24785165. And if you read Troy's original report you'll notice that the examples he shows of them succeeding come from other places than HN:

If there are botnets or rings escaping our attention and succeeding on HN, they would need to be several levels more sophisticated than that one.
One thing to realize is that HN's anti-abuse systems don't always reveal publicly that accounts or sites have been caught. It can often be more effective to preserve information asymmetry and fight the abuse in subtler ways.
Re Rohrschach: the fact that it's considered dodgy is part of why I use the analogy. Most internet speculations about bots, astroturfers, shills, spies, brigaders, foreign agents and all the rest of it, are way dodgier than that.
