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.
