Bot verification

This User-Agent declares a bot or user-triggered fetcher. Each connection's IP is checked at ingest against the verification channels the operator publishes — its crawler IP ranges and, where documented, forward-confirmed reverse DNS. A claim either channel confirms is identified; one confirmed by neither — outside the ranges, inside a different operator's, or failing the DNS check — is an impersonation signal. Meta publishes its network rather than crawler ranges, so its identified claims are network-confirmed and its unconfirmed misses are unverified claims, not proven spoofs. bot-claim anomalies →

Co-observed signals
