MP Toolkit: Scam Shield for Marketplace

About

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.
