Okay, I need a reality check about how defederation works:
Say, Instance A defederates from Instance C, but there is an Instance B that federates with both.
Can people with accounts on B boost toots from people on A into timelines of people on C?
Can this happen the other way: toots from C boosted by B into A's timelines?
As far as I know...
If it's a suspension the boosts wouldn't be visible on A. Nothing from C would be visible on A under any circumstances.
If it's a silencing, I think the boosts are only visible to people on A if they are following the person on B who is doing the boosting.
@FediThing I mean defederation, so suspension I guess.
The naming change (block->suspension, mute->silence) hasn't helped this confusion sadly.
