The architecture. Posting requires GPS presence at the moment of posting. Events are GPS-verified at check-in. There is no way to participate in a neighborhood you cannot physically reach.

Bots don’t have neighborhoods. No prompt can generate a GPS location. No script can show up at the cafe on Tuesday. Authenticity here is not a content moderation policy. It is how the system works at the structural level. And spam does not work either. Posts only count when other neighbors actually engage with them, which means flooding the feed accomplishes nothing.
