design is very important, the design of a client can encourage toxic behaviour and ruin the experience for lots of people. Why do you think people say nostr is a pleasant place?
if i created a “fuck you” button that sends “fuck you” to people as a reply, this is an example of a design that would make this place less pleasant. I have a lot of power and i’m trying to wield that in a way that makes this a fun place to be.
If you disagree with this, you or anyone can make a client that implements these things, noone is stopping you. In fact, i believe amethyst does implement this? Which is why I seem to get cowardly anon replies that attack me all the time.
