Fraud prevention
Review the signals a marketplace owner needs before launch: account behavior, listing risk, bid integrity, offer abuse, payment-risk review, message safety, hub evidence, and approval ownership.
Account Signals
- Buyer trust and seller standing guide bid limits, offer limits, pickup release, category access, and support escalation.
- Review state should show the affected action, reason, owner, customer notice, seller notice, next step, and expiration.
- Launch controls should avoid unnecessary data collection and focus on marketplace actions, account history, and support evidence.
Listing Risk
- High-risk listings can be reviewed for missing proof, repeated media, restricted terms, category mismatch, unusual price, and report history.
- Seller-facing fixes should explain which image, serial, certificate, size tag, accessory photo, or condition note is needed.
- Visibility changes should stay attached to the listing, seller dashboard, staff queue, and policy history.
Bid Integrity
- Auction review should cover bidder eligibility, rapid bid jumps, repeated retractions, reserve closeout, seller cancellations, and support holds.
- Paused auctions need buyer-visible and seller-visible status that explains what is being reviewed and what happens next.
- Closeout records should keep the bid history, reserve state, top bid, seller standing, and support decision together.
Offer Abuse
- Offer controls should surface repeated low-quality offers, off-platform pressure, aggressive message patterns, and proof-avoidance behavior.
- Sellers need clear options to accept, counter, request proof, report, block, or send the item to hub review.
- Support should see offer history beside messages, listing proof, buyer standing, and seller response quality.
Payment-Risk Review
- The current demo does not move money, but launch review should plan authorization holds, refund routing, seller release timing, and chargeback evidence.
- Risk signals should separate checkout review, wallet credit use, refund patterns, seller holds, and payout-readiness checks.
- Customer notices should be clear about whether an item, bid, order, refund, or seller release is paused.
Message Safety
- Message review should flag off-platform pressure, payment requests, suspicious attachments, repeated harassment, and unsafe pickup instructions.
- Customers should be able to report, block, attach evidence, and keep the report tied to the order or listing.
- Private support notes should stay separate from buyer messages, seller messages, and public listing details.
Hub Evidence
- Hub notes can confirm item intake, photos, accessory counts, serials, certificate checks, packing status, and QR release timing.
- Local evidence helps separate seller description issues, shipping damage, pickup mismatch, and buyer misunderstanding.
- Hub staff should see only the records tied to their role, service area, and active queue.
Owner Approval
- Owners need launch gates for account review, listing holds, bid review, offer abuse, payment-risk review, message safety, hub evidence, and appeals.
- Every rule should have a customer-facing explanation, staff owner, appeal path, retention note, and route where the evidence appears.
- Launch should keep browsing open where possible while pausing only the action that needs review.

Current demo state
Fraud prevention is represented as connected review evidence.
The static demo connects account signals, listing risk, bid integrity, offer abuse, payment-risk review, message safety, hub evidence, and owner approval using seeded routes.
Future platform state
A launch needs staffed review and enforceable controls.
Launch-ready service needs event monitoring, action holds, staff permissions, customer notices, appeal history, evidence retention, rule versioning, and owner-approved thresholds.
