MP Toolkit: Scam Shield for Marketplace

Scam detection for Facebook Marketplace. Trust scores for listings + SafeTrade buyer risk scanning in Messenger and sidebar chat.

MP Toolkit: Scam Shield protects you on both sides of every Marketplace deal — whether you're buying or selling. 🛡️ LISTING TRUST SCORES (For Buyers) Browse Marketplace with confidence. Every listing gets a real-time trust score based on 6 weighted factors: • Account Age — flags sellers with accounts under 6 months old • Listing Quality — checks description, price, condition, and completeness • Photo Analysis — counts photos and checks for image quality issues • Location Check — detects vague or suspicious location data • Seller Reputation — evaluates ratings, review count, and response time • Scam Pattern Detection — scans for 55+ known scam phrases across payment fraud, shipping scams, verification tricks, and urgency tactics A color-coded trust banner appears on every listing: Green = safe, Yellow = caution, Red = high risk. 💬 SAFETRADE: BUYER MESSAGE SCANNER (New in v3.0 — For Sellers) Sellers are targets too. SafeTrade scans buyer messages in real-time for fraud patterns before you fall for a scam. Works in 3 places: • Facebook Messenger conversations • Listing sidebar chat on your detail page • Seller dashboard conversations Detects 28+ buyer scam patterns including: • Payment fraud — Zelle, fake checks, gift cards, wire transfers, crypto, overpayment • Social engineering — urgency pressure, sob stories, too-easy agreements • Logistics scams — proxy pickups, fake movers, address redirects • Verification theft — Google Voice codes, phishing links, fake identity checks • General red flags — off-platform requests, email/phone harvesting A color-coded shield badge appears in every conversation: Green = safe buyer, Yellow = proceed with caution, Red = high risk. 🔒 100% PRIVATE — ZERO DATA COLLECTED Everything runs locally in your browser.
