idea for the "nsec to real artist-service":

- this service gives out a OTP to anyone who claims to be the real artist.

- the one artist who successfully publishes this OTP on his Spotify Account (i.e. via the profile description) is the winner.

Later: real artist with his given nsec changes his npub/nsec so it is truely private and the "nsec to real artist-service" is out of the loop for sure.
