Sounds like a job for an agent, “keep an eye on posts and assess against guidelines”.
I get that you might not want to repeat the many missteps of Social Media 1.0. And adding a ‘report’/‘block’ feature might feel like the beginning of a road nobody here (your friends and extended friends) wants to travel.
I’m guessing any moderation would be at the app level as the ultimate source of truth is what’s in the various RSS feeds? So… a block is not a block if someone can find it on the .rss? Although people can edit anytime, right?
So many cans, so many many worms.
