Meta is introducing new scam-detection features across Facebook, WhatsApp, and Messenger to enhance user safety. Facebook will implement a warning system for suspicious friend requests, alerting users to accounts with few mutual friends or unusual locations. WhatsApp will provide alerts for suspicious device-linking attempts, informing users of the request's origin. Messenger will expand its scam detection system to more countries, analyzing conversations for scam patterns and providing warnings. Over the past year, Meta has removed over 159 million scam-related ads and deactivated millions of scam-related accounts.
