Marketplace listing photos can be AI-generated, stolen from retail websites, or taken of a completely different item than what's being sold. Before you send money to a stranger, run through this checklist.

Facebook Marketplace has become one of the most common venues for online purchase fraud. The FTC reported in 2023 that consumers lost $2.7 billion to social media fraud — and online shopping fraud was the single largest category, with Facebook specifically named as the most frequently reported platform.
The listing photo is where most Marketplace fraud begins. A convincing photo — whether it's a stolen stock image, a picture of a different item, or increasingly an AI-generated product image — is what gets a buyer interested and willing to send money before they've seen the real item. By the time they realize the photo didn't match reality, the seller is gone.
AI-generated product photos add a new dimension to this: scammers can now generate a photorealistic image of a designer bag, piece of furniture, or electronic device in minutes, without ever owning the item. These images can look more polished than real photos, which is itself a warning sign.
Work through each of these on every listing where real money is involved. More red flags doesn't always mean fraud, but each one narrows the odds that the listing is legitimate.
1. Only one or two photos
A real seller who owns the item can photograph it from every angle. One photo — especially a single perfectly composed shot — is the most common signal of a fake listing. Genuine secondhand sellers typically post 4–8 photos showing the item from multiple sides, any visible wear, and the actual condition.
Check it: If there's only one photo, ask the seller for more before engaging further.
2. The photos look too professional for a person-to-person sale
Studio lighting, a white background, and professional-quality photography are normal on Amazon. On Marketplace, where someone is selling a used couch or a secondhand phone, a professional product shot is suspicious. Real sellers photograph items on their kitchen table, in their garage, or in natural light — not on a white seamless background.
Check it: Right-click the listing photo in Chrome → Investigate with Faux Spy — AI-generated product photos often return a clear AI verdict.
3. No photos showing actual condition — no wear, no damage, no setting
A used item has a history. Legitimate sellers who actually own what they're selling will photograph it in context — on their shelf, with visible use, or with any damage they're disclosing. Photos with no background, no environment, and no evidence of use are not photos of a real item in someone's possession.
Check it: Look for at least one photo showing the item in an actual room or environment, with natural shadow and lighting.
4. Reverse image search returns the same photo elsewhere
The most common type of Marketplace photo fraud is stolen images: a scammer copies product photos from a retailer's website, another person's legitimate listing, or a previous sale on eBay and posts them as if they own the item. A reverse image search catches this immediately.
Check it: Right-click the photo → Search image with Google. If it appears on a retail site or in other listings with different sellers, it's stolen. Use this alongside Faux Spy — reverse image search catches stolen real photos; Faux Spy catches AI-generated ones.
5. The listing photo has a watermark, logo, or website URL
A watermark from a stock photo site, retailer logo embedded in the corner, or a visible URL in the image is direct evidence that the photo was copied from somewhere else. This is one of the most obvious signs, but it's still worth checking on every listing where the photo quality seems unusually high.
Check it: Look at all corners and edges of the photo at full size for any embedded text, logos, or watermarks.
6. The photos show a location inconsistent with where the seller says they are
Sellers on Marketplace set a pickup location. If a listing is set to your city but the photos show license plates, outlet socket styles, or storefronts from a different country, the photos weren't taken locally — and the listing may be a remote scam where no in-person handoff is ever going to happen.
Check it: Look at background details — outlet types, signage, vehicle plates, retail brands visible in storefronts.
7. The seller's profile photo looks AI-generated
Scam accounts on Facebook often use AI-generated profile photos because they're harder to trace than stolen real photos — a reverse image search of a real person's photo can expose the theft, but an AI-generated face has never existed anywhere online. A synthetic-looking profile photo alongside a suspicious listing is a strong combined signal.
Check it: Click through to the seller's profile, right-click their profile photo in Chrome, and run Faux Spy on it. See also: how to detect AI-generated profile photos.
8. The listing photos look AI-generated
AI-generated product images are now common enough to be a genuine Marketplace risk. A generated image of a luxury item — a handbag, watch, piece of furniture, or electronic device — can be photorealistic to the naked eye. The giveaways are often subtle: perfectly uniform backgrounds, slightly wrong material textures, or product details that look right in aggregate but wrong on close inspection. A detection tool is faster and more reliable than visual inspection for catching these.

If you've run through the checklist and you're still not sure, ask the seller for a verification photo: the specific item they're selling, held in their hand, next to a piece of paper with your name and today's date written on it.
This is not a suspicious or unusual request — any legitimate seller will understand why you'd want to confirm the item exists and is in their possession. A scammer cannot produce this photo because they don't have the item. This single request eliminates photo fraud completely.
If the seller refuses, deflects, or disappears after you ask, that's your answer.
If you paid for a Marketplace item that wasn't what the photos showed, or that was never delivered:
Run a reverse image search using Google Images — if the photo appears on a retailer's site or in other Marketplace listings from different sellers, it's stolen. For AI-generated photos, right-click in Chrome and use Faux Spy to check. Real listings almost always have multiple photos showing the item in an actual home environment with visible signs of use.
Yes, and it's increasingly common. AI image generators can produce convincing product photos of items the scammer doesn't own. The result often looks more professional than a real person's casual snap — which is itself a red flag. Faux Spy detects AI-generated images directly on Marketplace listing pages in Chrome.
Yes — Faux Spy works on any image visible in Chrome, including Marketplace listing photos and seller profile pictures. Right-click the image, click Investigate, and you'll get a verdict in seconds. No uploading, no switching tabs.
Stolen photos — copied from a retailer's product page or a previous legitimate listing — are the most common type. These look professional because they are: they were taken for a real product. A reverse image search immediately exposes them. AI-generated product photos are the newer and harder-to-spot variant, which is why a detection tool adds value the reverse image search can't provide.
Don't pay. Ask for a verification photo — the item in the seller's hand next to a piece of paper with your name and today's date written on it. Report the listing to Facebook. If you've already paid, file with the FTC at ReportFraud.ftc.gov and contact your bank or card issuer immediately.
For many transactions, yes — but it requires the same diligence you'd apply to any online purchase from a stranger. Always meet in person for high-value items, pay by card rather than peer-to-peer apps when possible, and use the verification steps in this guide before sending any money. The risk level is higher for listings where the seller insists on shipping only and refuses in-person pickup.
