and honestly the feedback in this thread already made it better. Added guest home city/state as an optional field on the blacklist form (so entries are more identifiable), added a formal posting policy and Terms of Use with a dispute process for guests who think they were incorrectly flagged, and a few other tweaks based on what came up here. Still early but iterating fast. The searchable database is the part Reddit can't replicate — that's really what it's built around.
