That tells you about false positives — things caught that shouldn't have been — and nothing at all about false negatives, the abuse that sailed through unflagged. Those are invisible by definition: no flag, no queue, no complaint until a user makes one. ## The view * Filter **Flag status → Not flagged**. * Set **Ordering → Random**. Random ordering is what makes this a sample rather than a reading of your newest traffic, which skews by time of day and by whatever campaign is running. ## Working it This view never empties, and it isn't supposed to. Treat it as a standing habit: someone reviews twenty items a week and corrects anything that should have been caught. Those corrections are the point. They feed [adaptive optimization](/custom-models/adaptive-model-optimization), which is how the gap you just found stops being a gap. Narrow it to one channel or content type if you have a specific suspicion — sampling everything at once takes a lot of items before it says anything.
