Nostr should be like the Matrix... Anyone can participate, humans, bots, old programs, the french guy, the architect, agents, the oracle, machines, etc... BUT to do so, you must come up to "broadcast depth"... There is inherent risk here, but also assurances that anyone and everyone can hear you including sentinels in machine city as well as humans in zion... You may see, hear or experience things that are disagreeable, but YOUR message WILL be heard by someone. Below/outside the wild wild west of broadcast depth are "public forums" like the train station or the Adam's street bridge where stressful things like debates can take place.  Below/outside of this could be arenas where conflict resolution or fights could happen like the agent training program or the agent park fight lot.  Then we can "safety zones" such as the Oracle's apartment for adepts or the back halls of the keymaker.  Filtering should be completely in the hands of the user so that they can remove the filters/blinders at any time if they so choose.  The Matrix IS a system of control... The question is, whose control?  Make nostr controlled from the bottom up and the outside in...
