Paste a marketplace listing URL into SilentID Deal Scanner and you’ll get a verdict in seconds: Looks fair, Suspicious or Likely scam. It runs 14 fraud-signal checks — price vs UK market range, account age, image reuse, message-only seller and more — and it’s free, with three checks a day and no signup.

Why a price-and-scam check matters

TSB’s 2025 fraud data shows that 1 in 3 Facebook Marketplace ads could be a scam and that £160,000 is stolen on Marketplace every single day in the UK (Source: TSB). The single most-effective signal? Price. The classic listing pattern is a real product, real-looking photos, and a price 30-50% below market — designed to bypass your scepticism for long enough to extract a deposit.

A spreadsheet check for “is this iPhone in the right ballpark?” isn’t enough on its own — but combined with account age, image reuse and seller behaviour, it catches the vast majority of UK marketplace fraud before money moves.

Deal Scanner
A free SilentID tool. You paste a UK marketplace listing URL and it returns a fair-price band from live UK market comparables, runs 14 fraud-signal checks, looks up the seller’s TrustScore, and gives you a one-line verdict: Looks fair, Suspicious, or Likely scam.

The 14 signals Deal Scanner checks

Each signal is weighted — a too-good-to-be-true price plus an account younger than 30 days is much more damning than either alone.

  1. Listed price more than 30% below the market range

    A £900 iPhone 15 Pro listed at £450 isn't a bargain — it's the most reliable signal of a wire-fraud listing. Deal Scanner flags any item priced below the 30th percentile of the comparable UK market range.

  2. Account age under 30 days

    Brand-new accounts post-and-vanish. Combined with a too-good price, account age is the single highest-correlation scam signal in TSB and Cifas data.

  3. Reused or stock-photo images

    Reverse-image search finds the same photo on a manufacturer site, an eBay listing in another city, or a Pinterest pin from 2019. Real second-hand items have hand-held, slightly-imperfect photos.

  4. No location or vague location ("Anywhere UK")

    Genuine in-person collection listings have a real postcode area. "Ships from anywhere" + "deposit before viewing" is the wire-fraud playbook.

  5. Description copy-pasted from a manufacturer page

    Real sellers describe condition, scratches, why they're selling. Marketing-copy descriptions = scraped listing.

  6. Seller wants to move off-platform immediately

    WhatsApp before the meet, Telegram, "DM me on Instagram" — every step off the platform strips your fraud-recovery options.

  7. Bank-transfer-only or PayPal Friends & Family

    A seller refusing PIN Pickup, eBay Managed Payments or PayPal G&S is a seller refusing to be held accountable.

  8. Pressure: "Three other people are interested"

    Urgency manufactured to skip the inspection step. Honest sellers are happy to wait an hour for a real meet.

  9. Asks for a holding deposit

    Action Fraud lists "deposit-to-view" as one of the top three UK marketplace fraud patterns. The deposit is the entire scam.

  10. Too many identical listings in different cities

    A single seller posting the same TV in Manchester, Cardiff and London = listing factory.

  11. Newly-registered domain or non-marketplace URL

    Some scammers post a real platform listing then redirect you to a lookalike "secure-payment" website. Deal Scanner WHOIS-checks every link in the listing body.

  12. Reviews and feedback do not match the seller name

    Account name "Sarah J" but the public feedback is on "ElectronicsWarehouse2024" — repurposed account.

  13. Listing posted from outside the UK

    IP geolocation on the listing metadata vs the stated UK location. Common pattern for VPN-hidden international fraud rings.

  14. No prior Trust Passport or verified marketplace profiles

    A seller with zero verified history asking for hundreds of pounds is — at minimum — a seller you should meet in a Safe Trade Zone with PIN Pickup.
