This is answered under the subheading "Why not just invest in more moderation?".
comp.lang.c++.moderated used a system where submissions needed approval by the moderator(s) before posting. It worked well for many years. The delay could be up to a day, but people accepted that.
After all, it's like the pre-internet "Letters to the Editor" section of the newspaper.
I don't see any words like that in what I posted.
comp.lang.c++.moderated is not a good example, that's a niche topic with relatively high barriers to entry. On mainstream news websites a big story can attract hundreds of comments a minute.
