# Relays as PrivaPub reads them (Federation:Relays in appsettings.Pasture.json): Activity-Relay, which forwards what its
# subscribers send, and aode-relay, which announces it. For each, the instance actor subscribes, Mastodon subscribes too,
# and a public post of a Mastodon account nobody here follows reaches PrivaPub's federated timeline through the relay;
# nothing of a persona's goes to a relay. Mastodon leaves each relay after, so the town sees no relayed posts. Needs the
# relay, aoderelay and mastodon peers.
