If Google wanted an official account then no one would be confused at a nip-05 verification there.
Lyn, presumably, has people who are familiar with her. With her website and blogs. So verifying there is a wonderfully simple solution. Yes, a random person might mistake a different nip-05 verified account just like a lot of people mistake parody accounts for real account through other social media mediums.
An influencer without a domain can publish their npub on any of their other accounts to verify that it’s them. Seems simple enough.
Aside from public figures, I can’t think of a better way to verify yourself while maintaining anonymity than nip-05.
