It's cool. They don't want to dox where they're from by posting a local radio station. (Though the radio station host that joins Nostr may do just that anyways.)
ah, ok. that makes sense.
nostrmeet.me will allow for “anonymous” invites, providing advocates a means to onboard locals that they know “personally” into their own web of trust (“my” recommended nostr content, accounts, and apps vs “global on your own” nostr) without revealing their connection to the “new account” on Nostr.
