Fediverse makes the indexing question interesting because some people don't want it deeply indexed: they point to the practice of dredging up old opinions on Twitter as an anti-pattern that the tooling should not support. Indexing without permission is met with hostility / defederation over there, and both individuals and server owners have tools to switch fine-grained indexing on and off. (It is, of course, fundamentally impossible to keep people from indexing a default-open network, but if one does it, one does not advertise doing it outside the service-supported mechanisms).
