If lemmy instance ‘A’ defederates from instance ‘B’, but ‘B’ doesn’t explicitly defederate from ‘A’; can the users on instance ‘B’ still see the content from ‘A’, but not interact? Or are both sets of users prevented from seeing each others content altogether?

Eithers users could visit the domain directly ofc, I’m just curious if ‘B’ still retrieves the content from ‘A’ to show in user feeds.
