Why Hacker News doesn't need CAPTCHA
(because, sssh, nobody does)
The independence from captcha is a significant win for HN and an open Internet.
But seriously, how do you do it? It would be great for other sites to take note.

The reason HN does not need a captcha is that it has 2 full time moderators that watch this site continuously. They do an incredible job at weeding out abusive content. There is some automation that also helps them flag the obvious abuse and people can also flag submissions to help that system. If you enable "show dead" in your profile, you will see some of the content that gets removed.
I'm told that hCaptcha would be better than you-know-who but haven't had the cycles to look into it yet.
The enterprise version is probably what you want: includes a "99.9% passive" mode where most people will never see a challenge unless they look like an attacker, meaning you can leave it on all the time rather than having to firefight.
