There is an archiveteam project to index all the shorteners and where they direct to. I think it's the default project if you're running the warrior and there's nothing more important going on.

This was predicted and warned about when the link shorteners first appeared, decades ago.

But people keep using them (for a while for Twitter, but maybe mainly for analytics, though they could self-host and accomplish the same thing).

Infact this is a problem that we'll face someday.
