How does one downvote a comment on HN? I thought maybe there was some reputation or age requirement, but I've been here a while now & I still don't see any option to downvote comments.

How many Karma points do you have? (top right). I don't think I could downvote until I got to about 1000 or 1500 points, I believe.

I feel that it should actually be raised to over 9000.

I'd downvote this if I could

[Semaphor]

I think you need over 500 karma to downvote. I couldn't downvote for my first few years here (and I probably only downvoted posts once or twice since I could)

The threshold is at 500 karma points.
