Illegal in which nation state? Nostr is a permission-less protocol.
While I feel there is content that is very distasteful it is not up to me, rather the individual relay operators to police their own in and out flows.
Open free networks cut both ways
Great point. All responsibility is on the individual relay operators. This is why relay operators as there relay becomes more popular, they will need to hire moderators to help ensure illegal content is not staying on the server/relay. Is there a way on amethyst I can see what relay a note is residing on? This would help determine which relays I should have download turned on or off.
