@fulanigirl @atomicpoet @kraft @fediversenews I'm looking forward to seeing it too, since it's an interesting user experience problem.
I'm not sure it's possible to turn off replies to announcement posts entirely, but a Fediverse server could well decide not to relay them unless given the okay manually. (This means they'd at first be visible only to the commenter, their followers, and others on the same instances as either. Edit: and optionally on the rendered blog page I assume, since that part can be easily revoked and doesn't "spill" them elsewhere.)
I don't think it would be technically possible to widely hide them again once relayed, due to how authorisation works. I haven't checked too closely, though.
Ideally it should be possible to report comments to their origin instance's admins, since afaik *they* do have the power to wipe a post across the network relatively well. Mastodon has that feature, but I've seen some other implantations gaining it only week or so after launch.
@Qazm @atomicpoet @kraft @fediversenews yeah, it's an interesting issue. And I suppose that might create more work for the server administrators. For people whose WP sites are for marginalized folks that might be problematic.
