This is an important question, I'm surprised to see it downvoted. That being said, I would imagine it would be done the same way as an automod type bot for any Matrix room. You'd probably have to implement it yourself though. Edit: That being said, I don't like the idea of automatic moderation. For small scale blogs, maybe just a manual approval of comments would be worthwhile.
