Local-first scam screening assistance for Facebook Marketplace sellers. ScamShield helps Facebook Marketplace sellers evaluate potentially suspicious buyer messages before responding. The extension analyzes supported Facebook Marketplace and Messenger conversations for common warning signs associated with scams, spam, suspicious transaction behavior, and automated or template-style messages. ScamShield presents its findings as an easy-to-understand risk assessment to help sellers make more informed decisions before continuing a conversation. Key features include: • Scam Risk scoring for supported buyer messages • Bot Likelihood assessment • Identification of suspicious message patterns • Detection of urgency and pressure tactics • Detection of attempts to move a transaction off-platform • Identification of generic or template-style buyer messages • Clear explanations of the indicators contributing to an assessment • Local-first processing designed for Facebook Marketplace sellers ScamShield is an informational screening tool. A low-risk result does not guarantee that a person or transaction is legitimate, and a higher-risk result does not prove that a person is attempting fraud. Users should use their own judgment and follow applicable marketplace safety practices when communicating or completing transactions. ScamShield is an independent browser extension and is not affiliated with, endorsed by, or sponsored by Facebook or Meta.
