oh cool, glad you tried it. The moderator setting just allows that other person to nostr login, and they can manage the relay that you've created (they get the same config screen you see here). Right now it's read-only cause I have to fix the perms. The only moderation options are what you see there, you can block keywords or pubkeys, or you can run in 'deny' mode and allow only certain keywords or pubkeys. I want to improve on this and add more options, but this was the basics.
I want to integrate this with nostr lists, so that you can use them to bulk-add to the different filters, and I'd also like to have delete available as well, so that anyone in the owner or moderator crew can submit a report via their nostr client and an agent will be listening and perform the moderation action on the relay by deleting the messages retroactive.
