Why would I, as a site owner, want to cede control of the comments that are associated with my site? If, for example, a comment was just a string of racial slurs, there's no way in hell I would want that associated with my site, and I would want that deleted as soon as possible, regardless if you would want to see it.

What hello_there proposes is a comment system that is not associated with your website. It would akin to having an article of your website linked to a subreddit and people commenting on it.
