Hi dear Nym Community,
a while ago I started to publish a warrant canary at my website, to let Castor users know that no requests have been made, which hopefully is good enough for your privacy, when sending anonymous emails or Usenet postings via the Nym Mixnet through my Hermes email gateway in Hungary and which keeps no logs.
My warrant-canary.txt file is signed with yubicrypt, which is a modern replacement for OpenPGP usage and you can download or copy/paste the data and verify it with yubicrypt, without having a Yubikey.
Best regards
