Ahhhh... ok, got you. That's something separate, nothing to do with the Fediverse as such.

It's due to lack of "backfilling" on a federated system.

If an account has never been followed or shared by anyone on your server before, it will appear to be blank. If that happens, the current behaviour of Mastodon is to link to the account's public page on its home server. This public page is up to date, but the downside is that because it's not on your server it's fiddly to interact with.
