AI Content Moderation for Marketplaces
Keep your e-commerce platform safe by moderating product listings, user reviews and seller messages automatically, at any volume.
The Challenge
A single scam listing, fake review or fraudulent message can undo months of trust. Manual moderation can't keep up as the marketplace grows, and rigid keyword filters produce too many false positives.
The OpenModeration Solution
AI reads listings and messages in context, and the Action Engine hides high-risk ones automatically. Edge cases are handled by our team, and you see every decision in real time.
The Result
Your team spends far less time on manual reviews. Every decision keeps its written reason in a traceable history built for the DSA, and problems are caught before buyers see them.
Moderate every surface of your platform
Buyers and sellers talk in listings, reviews and messages, and each needs moderating. OpenModeration covers them 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 so buyers can trust what they read.
Seller messages: Watch buyer-seller messages for harassment, attempts to move the sale off the platform, and fraud.
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 items in one batch (listings, reviews, messages, descriptions) and OpenModeration flags scams, prohibited items and fake reviews. Results appear in your dashboard in real time, and doubtful cases are handled by our team.
One bad listing costs more than a thousand good ones
Buyers who run into a scam or a flood of fake reviews don't come back. Regulators now also watch 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
Clear scams are hidden instantly, and borderline cases are reviewed by our team, while you see everything in real time. Every decision is logged for DSA compliance.
Marketplace moderation FAQs
Can one tool moderate listings, reviews and buyer messages in one place?
Yes. Listings, reviews and buyer-seller messages go through the same API, the same rules and the same human review by our team, and you see everything from a single dashboard.
Can it catch off-platform payment requests and scam links in marketplace chats?
Yes. Describe the pattern in plain language as a custom category ("asks to pay outside the platform", "shares an external payment link") and the AI flags it even when scammers rephrase. Known domains and phrases can also be blocked by the word pre-filter before any AI call.
How do you avoid wrongly removing legitimate seller listings?
Each rule has two thresholds. Only clear-cut cases are hidden automatically; everything in between is reviewed by our team. You see the reason behind each AI decision in real time, can override it, and every override is logged.
Can we start with reviews before moderating messages?
Yes. You choose what you send to OpenModeration. Many teams start with one surface such as reviews, check the results in the dashboard, then add listings and messages with the same rules.
Can I moderate my entire existing catalog?
Yes. The batch endpoint processes up to 10,000 items asynchronously, which works well for a first pass over existing listings, reviews and messages. Results are pushed to your webhook when ready.
What happens to borderline listings?
You decide per rule: above a threshold, auto-hide or delete; below it, held for review by our team. You see the AI's reasoning in the moderation console and can override it, and every override is logged.
