Despite my impulsive answer, I'm going to leave this reply up because it is how publishing to aquatic chicken works. Anyone outside of it's (my) WoT would need to pay for access to post there but it's a huge number of people that are already allowed. ( If in doubt, check on the relay's homepage- https://aquaticchickentheory.nostr1.com -there is a search box to see if you're already on the allow list)
