I can imagine a kind of anti-spam federated reputation system that would work for the Fediverse, assuming anyone actually adopted it.
- Users can "Vouch" for others. A new activity type, it means you know the subject well enough to say they're a real person and not an outright troll
- For closed-registration servers, registration is a Vouch from an admin
- You can filter posts by users that aren't vouched for by someone N degrees of separation from you
