Im using Damus, primarily. I do t know that.  I would think that filtering should be done on the relay level. Having an assortment of PG, PG-13 and, R rated paid relays would provide a potential source of revenue for the relay operators as well as options for the users. People want different things so there’s a place for all of them. 

 Right. There is a way to accomplish filtering on relays and clients WITHOUT assuming the “legal” role of a publisher. This is the backdrop of the conversation above.  

 The nostr experience is 100% what the user makes of it.
