In #ActivityPub, once a post is federated, you lose control over how remote instances handle interactions on it. Some servers like #GoToSocial are working on interaction controls, but non-compatible instances simply ignore your rules.
With #HolosSocial, we're considering a "safe mode" available at publishing time. Your post would only be delivered to followers on instances that respect interaction controls. Not enabled by default, but there for those who need it.
If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/ap/users/115588590742214453/statuses/116076702509321775 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
