@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.
@huxley @TJ @vodamark @taylorlorenz my instance and/or client definitely has “Mute this conversation”.
One of the use cases for restricting replies is to counter & prevent misinformation from piggybacking on a conversation or announcement with a wide distribution / reach, so in such a case “Mute this …” would be insufficient.
