Subscribing to muting list of the other people doesn’t make much sense because we are all different human beings! You might easily be triggered by something I say and mute me, but John, for example, is fine with what I say to him and isn’t triggered. However, you've already added me to the list that someone will follow, potentially missing out on seeing my good side of personality.

I understand your point, but one cannot moderate all the spam that comes to Nostr if it becomes massive... I can't think of another simple solution without invading the individual freedom of the rest. In Bluesky I tried this on a smaller scale with the furries who were the largest community and between about 4 people without much work I managed to clean my feed
