imho this reflects a huge failure of the fediverse. Our accounts shouldn’t be tied to an instance that’s hosting content, they should be on a an auth-only server that only is responsible for managing our identity, separate from the content-servers. Then it would be up to content-servers to decide how much content they want to federate about an identity to show on that user’s profile-page on this particular content-server. Like either federating it right in (hey here’s @Pxtl’s profile/feed scraped from every fediverse server they use directly) or just autogenerating links to their content on other servers (we don’t want to host content from HowToBlowUpAPipelineLemmy.org on Lemmy.world but here’s a link to @Pxtl’s posts there).

Wouldn’t it be cool to have the same identity on Mastodon as on Lemmy?

Then you could continue to participate in the fediverse without creating a new user-account on every server. Of course, the auth servers would still be vulnerable to outage but since they’re lower load and just providing auth they’d be much less vulnerable.
