Because Discord is a proprietary glorified IRC SaaS; its contents are, by nature, ephemeral and under control of the vendor. I'd expect such links to rot very quickly.
Collaborating on Discord is fine. Important results, including citations backing them, should really be published or at least replicated in more durable medium that's less susceptible to link rot, and easier to archive. Today, that's PDFs in paper repositories, or even regular blog posts.
