You can follow KBIN magazines and Lemmy Communities from Friendica (they show as what they call "Friendica Forums") and you can do as you can block domain without loosing comments, block particular instances and or users (they still consider "forums" to be users, to simplify all the joining, subscribing, friending thing), and you can drill down on your own comments under your profile to see replies (I think you have to change a setting to see your replies in your default profile view) It's probably worth checking out https://friendica.fediverse.observer/
