(I'm not saying HN should do exactly the same thing, but one example is Slashdot's system where a comment can get downvoted in a way that tags it specifically as trolling/offtopic/whatever - https://slashdot.org/faq/mod-metamod.shtml seems to describe it alright)
Personally, I don't downvote anything unless it's either complete and utter bullshit (e.g. someone acting like PHP is bad based on arguments barely valid in the end of the PHP5 era), or it is plain and simple far-right/conspiratorial in nature. It used to be the case that this was how most people used the downvote feature.
Nowadays? Seems like the tide has shifted, and even completely legitimate viewpoints (not just on politics threads) get downvotes for unexplainable reasons. It saddens me a bit.

Such a thing exists. You have to open the comment's dedicated page by clicking on the timestamp; if you're over 500-1k karma you can then flag it. Enough flags auto-kill comments and they only appear for those who have "showdead" enabled.
This reminds of the 1-5 star rating system issues, and how people interpret it however they want without reading what it means. Let’s take Uber for example. I leave a 5/5 rating for a purely average trip where everything went as expected. Afaik, this is how Uber’s rating scale works (apparently drivers start getting warnings if they drop below ~4.5), so it surprised me when I once saw a friend give a 4/5 since the trip was “just normal/average”.
Conversely, let’s take Goodreads, where I feel that many people don’t read the definition of the rating scale and give star ratings not matching the definitions.
Goodreads definition is: 1 star="did not like it", 2 star="it was ok", 3 star="liked it", 4 star="really liked it", 5 star="it was amazing".
With that, if you simply found a book “ok”, you are to give 2/5. If you simply “didn’t like it”, then that’s a 1/5. It shouldn’t be unexpected to see many 2/5 and 1/5. And a 5/5 should be a rarity. Yet you if look at the actual reviews, feels like many people don’t follow the rating scale definitions and give it their own meaning.
