AI Content Moderation for Marketplaces
Keep your e-commerce platform safe and compliant. Automatically moderate product listings, user reviews, and seller communications at scale.
The Challenge
A single scam listing, fake review, or fraudulent message can erode months of trust-building. Manual moderation doesn't scale with marketplace growth, and rigid keyword filters create too many false positives.
The OpenModeration Solution
A complete moderation harness. Context-aware AI analyzes listings and messages, while the Action Engine automatically hides high-risk content. Edge cases are routed to a dedicated review dashboard for your Trust & Safety team.
The Result
Drastically reduce the time your team spends on manual reviews. Maintain DSA compliance with full audit trails, and protect your marketplace's reputation with proactive, intelligent moderation.
Moderate every surface of your platform
Marketplaces need proactive moderation across every user interaction point. OpenModeration handles it all from a single integration.
Product listings: Block prohibited items, detect scam patterns, and flag misleading descriptions before they go live.
Reviews & ratings: Detect fake reviews, hate speech, and spam in user feedback to maintain authentic community trust.
Seller messages: Monitor buyer-seller communications for harassment, off-platform diversion, and fraud attempts.
Batch back-moderation for existing content
Cleaning up months of history doesn't have to be a manual project. Submit up to 10,000 existing listings in one batch — reviews, messages, descriptions — and let OpenModeration flag scams, prohibited items and fake reviews. Results land directly in your review dashboard.
One bad listing costs more than a thousand good ones
Buyers who encounter a scam or a flood of fake reviews don't come back — and regulators are now watching how fast you remove them.
-
Fake reviews: industry estimates put 30-40% of online reviews as fake or incentivized, eroding buyer trust across your whole catalog.
-
Scam listings: prohibited items, counterfeit goods, and payment-diversion schemes slip past rigid keyword filters.
-
DSA pressure: marketplaces operating in the EU must act on illegal content and report on it — fines can reach 6% of global turnover.
Auto-enforce your marketplace policy
High-confidence scams are hidden instantly; borderline cases land in the review queue for your Trust & Safety team. Every decision is logged for DSA compliance.
Marketplace moderation FAQs
Can I moderate my entire existing catalog?
Yes. The batch endpoint processes up to 10,000 items asynchronously — perfect for a first pass over existing listings, reviews, and messages. Results are pushed to your webhook when ready.
How do I catch scams that keyword filters miss?
Scammers constantly rephrase. Use LLM-based moderation with a custom category describing your scam patterns ("payment outside the platform, too-good-to-be-true pricing"), or write them into your community charter for the Action Engine to enforce.
What happens to borderline listings?
You decide per rule: above a threshold, auto-hide or delete; below it, queue for human review in the moderation console. Moderators see the AI's reasoning and can override with full auditability.
