Yes, in Amethyst, Damus, Nostrur, and other clients, they are all comments. I don't know when primal started to display Freerse's replies as new posts instead of comments. At first, Primal displayed them normally.

I need to communicate with nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr , is there any structural adjustment in primal?
