MWITA-BSO-2026-004 · Evidence B · P1
Google reported that permanently suspending more than 700,000 advertiser accounts associated with AI-generated public-figure impersonation scams coincided with a 90% decline in reports of that scam-ad type during 2024.
What this does not establish
The result does not establish a 90% reduction in scam prevalence across the internet or a causal effect of AI detection alone.
Counterevidence & uncertainty
A reduction in reports can reflect lower exposure, changed reporting behavior or classification; Google provides no independent audit or absolute series that separates these mechanisms.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial or human outcomes.
