Scams move between Facebook, Messenger and WhatsApp faster than warnings do. A victim sees a paid ad on one surface, a friendly message on a second, and a payment request on a third and each surface warns, if it warns at all, about only what it saw itself. The existing warnings are per-chat and first-contact scoped, and none of them states its evidence. The operation is cross-product; the explanation is not. Reported losses to scams starting on social media run into the billions (the FTC's $2.1B figure for 2025 covers social media broadly, not Meta alone, and counts reported losses actual losses are higher). MetShield does not claim to end this. It claims a specific, buildable gap: warnings that carry the scam's context across product boundaries, with citations, rendered where the product already warns. MetShield is a proposed additional scam-protection layer for Facebook, Messenger and WhatsApp that carries a scam's context across product boundaries , one operation, three surfaces, one explanation and renders that explanation inside the warning the product already shows. It does not replace Meta's existing scam alerts: it renders underneath them. It does not read private conversations , the model is shown the correlation graph, not the conversation and it never stores personal data. When the evidence justifies a warning, it produces a card that names its signals and cites each one. When it does not, it produces nothing and records why.
