EXIF + duplicate detection
Every uploaded photo is run through an EXIF-integrity check (timestamp, GPS, manufacturer signature) and a perceptual-hash duplicate-detection pass against the existing image corpus.
Bid-velocity scoring
The Watchdog continuously scores bid velocity, IP geolocation entropy and account age. Anomalies are flagged to the admin Compliance Console in real time.
GenAI pre-flight
Every new listing is also scored by the GenAI direct watchdog before it goes live so policy violations and obvious fraud patterns are caught at submission time, not after publication.
