Anyone can claim to be Elvis Presley.
The only way to avoid that is to set up NIP-05 as I have done. Using your real name and a real name DNS domain, with an SSL Certificate from a Certification Authority. This way you can port your real world ID to DNS and from DNS to a pubkey via NIP-05.
Lots of people here donβt like that though, and prefer the anonymity of a nym, thatβs OK. But I think they run a much higher risk of impersonation because nyms are easier to steal, as they are created out of thin air.
It all depends on where you want to trace your sovereignty from, either from yourself or from a nym you created. There are pros and cons for each approach.
