Yes. You can collect a decent amount of metadata and use that to corelate an identity, though. That's hard to defend against. But... I am still a fan of various identity for various uses.

I want a verified account that verifies my upcoming nostr portal, nostr gaming project, future podcast, personal website, and other projects I am affiliated with in one npub.
It can show more of a trust across them and unifies the account as I wish. I could do individual accounts as the root domains and brand, but my administration account can be unified.
