I like the new comment section being separate from the main article (even on a separate domain!). I'm curious what happened with other reasons to disable comments back in 2017 (esp regarding moderation).
What worked for when humans were reading my blog, was to encourage people to write me y email and manually incorporate their comments into the article (together with my answer).
Requirement to send an email instead of submitting a form was indeed a big obstacle for bad comments. And volume of good comments was so low that it wasn't an issue to process them manually (anyway I wanted to answer them).
