Yet you are here, on HN, a forum with a code of conduct (they're called guidelines but the commenting rules constitute a CoC), and this CoC is enforced firmly.
I don't mean this in a snarky "get outta here" way, but: why are you here? Why not any other forum, tech-related or otherwise? Why not 4chan? Whatever the reason is, is the answer not quite likely to be at least in part made possible by the CoC and its strict enforcement?
You treat it like a coincidence that HN guidelines are called "guidelines" instead of "Code of Conduct". I don't think it's a coincidence. I think there's a certain kind of ethos behind behind any "Code of Conduct" process, and that ethos is not present on HN. And I'm really happy about that. I think HN moderation is amazing and it allows for conversations that you couldn't have anywhere else on the web.
