Trust scores for Poshmark, Mercari, Vinted, Depop, Grailed, GOAT, and TheRealReal — honest protection for resale shoppers and sellers.
Peer-to-peer resale has exploded into a $200+ billion market. Poshmark (NASDAQ: POSH before being acquired), Mercari, Depop, Vinted, Grailed, GOAT, and TheRealReal have built trusted platforms for buying and selling everything from streetwear to luxury handbags. These aren't sketchy operations — they're real companies with millions of users.
The challenge with P2P resale is that your transaction partner is another person, not the platform. Most are honest sellers. But scams happen at the individual level — counterfeit items, misleading photos, post-sale 'oops it broke in shipping' refund attempts, and elaborate authentication disputes. The platforms have buyer protection programs, but using them requires staying within the platform's rules.
This guide breaks down trust scores for every major peer-to-peer resale platforms platform, identifies the specific scams targeting users in this category, and gives you a simple framework to shop or use these services safely. Every recommendation is free advice — no upsells, no premium tiers, no data collection.
Below you'll find a complete trust score comparison, brand-by-brand breakdowns, the real scams to watch for (most aren't what you'd expect), a 5-step safety framework, and answers to the 12 most-searched questions about peer-to-peer resale platforms. If you want trust scores in real-time as you browse, the free Nudge Chrome extension is linked throughout. If you don't want to install anything, this guide alone gives you what you need to shop smarter.
The peer-to-peer resale platforms space has changed dramatically in the last 24 months. Regulators are paying attention. Lawsuits are mounting. Consumer awareness is growing. But scammers have evolved too — using AI-generated lookalike sites, sophisticated phishing emails, and social media manipulation to target shoppers who don't have the time (or money) to research every transaction.
What we've learned reviewing every major platform in this category: the platforms themselves are usually legitimate. Most are publicly-traded or backed by major institutional investors. They have lawyers, compliance teams, and regulatory oversight. The risks come from around these platforms — the impersonator sites that steal credentials, the misleading marketing tactics that trap consumers in subscriptions or debt, and the ecosystem of scams that prey on shoppers searching for deals.
The platforms you use every day are real. But the scams designed to look like them are getting harder to spot. Below, we'll walk you through exactly what to watch for, how to protect yourself manually, and the answers to your most pressing questions.

Each brand has a dedicated trust report. Tap any card for the full review.
Naver-owned (since 2023). 130M+ users. Real platform with strong buyer protection. Posh Authenticate verifies luxury items $500+. Watch for sellers requesting Venmo (against rules).
Full Poshmark trust report →Public in Japan, growing in U.S. Real platform. Watch for 'item not received' scams and sellers trying to communicate off-platform.
Full Mercari trust report →European-headquartered, growing in U.S. Real platform with €10B+ valuation. Counterfeit issues on designer items — verify seller history.
Full Vinted trust report →Etsy-owned (NASDAQ: ETSY) since 2021. Gen-Z focused vintage and resale. Strong fashion authentication on some items, weaker on others.
Full Depop trust report →GOAT-owned menswear platform. Strong authentication on Grailed Curated (premium) items, less protection on standard listings. Higher counterfeit risk on hyped streetwear.
Full Grailed trust report →Sneaker authentication leader. All items verified before shipping. Real platform with $5B+ valuation. Trust score is high but prices include markup for authentication.
Full GOAT trust report →NASDAQ-listed (REAL) luxury consignment. Authenticates every item. Real and reliable but pricing skews high — and authentication errors have been documented.
Full TheRealReal trust report →These are the actual risks in this category — not platform fraud, but ecosystem scams that target you as a shopper.
A seller messages 'let's talk on Instagram for a better deal' or 'pay via Venmo and I'll knock $20 off.' This is the #1 P2P resale scam. Once you leave the platform, you lose buyer protection. The 'discount' isn't worth losing your money entirely.
Coach, Gucci, Louis Vuitton, Nike, Air Jordans — all are frequently counterfeited on resale platforms. The fakes are getting better. For luxury items $200+, only buy from platforms with authentication (Poshmark Authenticate, TheRealReal, GOAT, Grailed Curated).
Seller posts pristine photos. Item arrives with damage, stains, or wear. Resolution often favors the seller if you don't have photos/video proof. Document the unboxing on video. File disputes within 3 days. Use platform messaging for all communication.
On Mercari and Depop, some scammers buy items, claim 'not received' to get refund, then keep the item. As a seller, use tracked shipping always. As a buyer, never let a seller convince you to skip tracking 'to save money.'
Now you know what to watch for. But scammers evolve every day — new lookalike sites, new phishing tactics, new manipulation techniques. You shouldn't have to remember every red flag every time you shop. That's what Nudge is for.
We built Nudge to be the permanent layer of protection between you and these scams. Real-time trust scores on every site you visit. Automatic warnings when something looks off. No subscription. No account. No data collection. The people most vulnerable to peer-to-peer resale platforms scams — older adults, lower-income shoppers, first-time buyers — are exactly the people who can least afford expensive security tools. Protection should be a right, not a luxury.
If you don't want to install anything, this 5-step framework gives you what you need. Follow this every time you use peer-to-peer resale platforms and you'll dodge 90%+ of scams in this category.
Never send money via Venmo, Zelle, Cash App, or PayPal Friends & Family. The 'discount' a seller offers for off-platform payment is the cost of losing all buyer protection. If they push for off-platform payment, walk away.
For Louis Vuitton, Gucci, Air Jordans, Rolex, or anything over $500 — use platforms that authenticate (Poshmark $500+ Authenticate, TheRealReal, GOAT, Grailed Curated). The 10-15% markup is worth not buying a fake.
Video the unboxing. Take photos of any damage immediately. Screenshot all messages. If you need to file a dispute, evidence wins. Without it, the seller's story often wins.
Look for: 100+ sales, 95%+ positive feedback, account age 1+ years, recent activity. Brand new sellers with great deals are often selling counterfeits. 'Top Rated' badges are earned, not given.
Some resale scams happen on lookalike sites (fake 'Poshmark deals' on social media). Nudge verifies you're on the real platform every time. Free, runs silently, no data collected.
This isn't a guide for industry analysts, finance professionals, or people who can afford to lose money on a bad transaction. This guide is for regular people who want to feel safe when they use peer-to-peer resale platforms.
It's for the grandmother who heard about Poshmark from her grandkid and wants to know if it's safe. It's for the college student trying to figure out if a deal is too good to be true. It's for the parent ordering for the first time. It's for the freelancer who depends on these platforms but doesn't have time to research every detail. It's for anyone who's ever asked, "wait, is this site actually legit?" — and didn't know where to find an honest answer that isn't trying to sell them something.
