Earlier I saw an #AskNostr  with a person asking if they should report illegal content on #Nostr.  

How does the reporting system on Nostr work? Is there a way that relays communicate with each other to flag 'illegal' content? 

What counts as 'illegal' content - since Nostr knows no jurisdiction. I am trying to understand how 'censorship' works here. 

It's curious because Nostr could become known as the armpit or 4chan of the internet. I'm wondering how a balance will be created - if at all.
