Yeah, this is something that can make or break NOSTR. We need lists of relays that have good filters for bad content so clients can have a standard "good relays" initial setup and we need lists of "suggested" blocks of users who are posting nasty things which Clients can implement as they see fit. Every client cannot put the time and effort into banning bots, people who post illegal content, etc there needs to be some shared effort to make "family safe" NOSTR. People who want illegal or offensive things can/will put the effort into finding the relays which allow whatever.
