Since news leaked out 2 days ago that Facebook has approached Mastodon developers and admins - requiring non-disclosure agreements first - the whole microverse (i.e. mastodon / pleroma etc, the micro-blogging part of fedi) has been talking about nothing but that and Facebook’s imminent entry into the fediverse with an as yet not clearly defined entity called Barcelona or p92. This woud be very roughly comparable to Reddit saying they are going to federate with lemmy.
Yet here on lemmy I could only find a relatively small discussion.

Did the lemmyverse not know or just not care that much?
is there an ability to block your content from being submitted to a specific instance (like a user side defederation?)
Not yet, but I do think that is something that should be implemented by Kbin/Masto/Lemmy etc regardless of what Meta does. There will always end up being instances that cater to niches that specific users won’t want to see/interact with. Again, personally I think that should be a user level decision, not a instance level one.
