Methods and caveats

What is a labeler? A third-party service that publishes tags (labels) about Bluesky posts or accounts. Clients choose which labelers to subscribe to and how to interpret labels (ignore / warn / hide).
This site observes labeler behavior only. No content analysis, no user profiling, no moderation actions.
Rules detect geometric patterns (rate anomalies, target distribution, churn). Thresholds are configurable.
Every alert includes a receipted hash over rule_id, config, inputs, and evidence for reproducibility.
Sparklines show hourly event counts over 7 days. Badges summarize which rules fired in the period.
Observation surface: label events from com.atproto.label.queryLabels and labeler declarations from com.atproto.sync.listReposByCollection. Does not observe content, profiles, or social graph.
Classification is based on structured evidence from multiple surfaces (registry declaration, DID document, endpoint probing, observed label activity). Each labeler page includes a "Why classified this way" expander with full evidence.
