A trivial amount you've had for ages (31 karma[0] - although it's not public, I'm sure the unofficial guides adjust accordingly)

I wonder why I've never had that ability then.

You have to click on the time of a comment (eg "2 days ago", "1 hour ago") to see the [flag] link, and you have to have show-dead turned on to see the [vouch] links. They're not super obvious in the UI by default, but you probably have the ability. You'll see a lot more bots/spammers/noise if you have show-dead turned on.

Wow thanks. I’ve probably spent a thousand hours reading hacker news comments and never noticed.
