There are many, many places where it would be impractical to regenerate and repost links frequently. Plus, regenerating a link would require a Discord API call, and they could easily rate-limit that or add anti-bot features, which would put a cap on how scalable an auto-refresher could be.
At some point it’d probably just be easier to create a service that generates the links on demand and caches them for their TTL. However, generating the links will probably require access to the Discord server where they’re posted.
