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.

If there at least was e-mail address to the artists, could send redeemable ecash by e-mail to them? Small sums for each anyway initially, but when artists see money coming...?
