The part I don't understand is how posting the link on HN is different from posting it on Github. I'm wondering for example if Github has some sort of extra bot protection HN does not, or if there's some cultural difference I'm not aware of or seeing.
Discord servers are more like a hangout place than a public forum and public invite links are like putting a key under a mat. Just because the owners of a Discord server put it on their public webpage or GitHub repository doesn't mean it's cool to spread it around willy-nilly.
There are also practical concerns. An invite link that needs to be deleted (for example due to spam abuse) means that it will no longer work. Updating all the places where that old link appeared to the new one can be impractical or impossible.
