@BeAware yeah- I think the way that fedi works currently - doens't really allow someone to truly kill discussion- as that reply was likely pulled in through a relay or someone you follow posted it, or whatever.
What I don't want to see here is mastodon servers federating the replyiblity outside of their own silo.
No reply data is gathered from the mastodon server in the first place- So I just hope they don't change the fact that people can reply to the post in the first place.
I wish for something where they can limit it for them, but not anyone else, as that would fundamentally kill the idea that each server hosts their copy...
