Creating ban lists, mute lists is not really something good. Its typical of the cancel culture. There were threads on Nostr discussing mute lists on BlueSky.

Its alright when people personally use to mute people they don't want to see but when it becomes mass feature it will cancel many just by default. And I think thats not right. Especially for Nostr where freedom of speech value is supported by majority. My solution is not to mute actually. I have my own groups of people and I still read from time to time people who disagree with me.
