effective_family sometimes contains the relay's own fingerprint
This was originally reported as a Relay Search bug #25034 (moved).
Sometimes, but not always, the effective_family for a relay will include the relay itself. The specification does not explicitly say that a relay's own fingerprint will or won't be included, but from reading it I would assume that it is not included.
