@TJ @vodamark @taylorlorenz Yes. Twitter’s “Only People Mentioned Can Reply”/“Only Followers Can Reply” was:
1: developed to mitigate noise/spam/dog piling/harassment/protests without dedicating policy (& human labour for actioning) to AUP violations;
2: needed a central technological access control system to enforce it.
If it were written into the specification … it might not be honored by some instances, but that could be a defederation condition.

Not really. We already can kinda have it in some way:
a) the canonical view of the thread is served by your instance, so it can refuse to publish some replies there (using whatever internal logic it wishes to use),
b) when a reply is sent to the OP's followers, if the OP's followers list is not public, it's the OP's instance that does that forwarding (and can choose to refuse to do so based on any internal logic it uses).
If OP's instance is Mastodon/Pleroma/Akkoma and blocks (suspends) the domain of the replier, both of these things will happen. I don't know which kinds of other blocks (incl. in other instance software) will currently cause which subset of them to happen, but would hope that OP blocking the replier would also cause both to happen.
This obviously doesn't prevent the replier from sending that message to e.g. people explicitly mentioned. Alas, they could send such a message as a straight-up new message instead of a reply, and no reply-blocking would help with that (point (a) above already deals with visibility of that as a reply when viewing the OP's post).
