Until the NIP05 isn't valid, it's a scam π
Is this account on #Nostr impersonating official NSA account? nostr:npub15869nfhd78frevqt6wqmeglkskzgh3sezpmeucdev0z0as0fqjvspq6qwk

As I checked, nsa.gov is a valid, official website of the US government.

I'm not sure but this sort of accounts undermine #Nostr.
You're a bit of a snowflake
May be, may not be. Adjectives don't bother me. They just express to speaker's attitude.
But I'm not in love with the NSA. One can of course nick them. I'm not worried about mockery here. I'm thinking of impersonation. One can mock anyone without impersonation.
Don't get hurt, my fren. π«
