G2★★★★★(4.9)Highest Rated in Content Moderation

Content moderationfor marketplaces.

A buyer who gets scammed once doesn't come back. Lasso screens every listing for scams, counterfeits, and off-platform contact details, from the obvious fakes to the subtle ones: a lookalike logo, a phone number hidden in a product photo. Your team sets the rules and the thresholds. Buyers browse listings you can stand behind.

Keep every deal on-platform.

Off-platform deals cost you the fee and the buyer protection. Lasso detects phone numbers, emails, payment handles, and links in messages, titles, and images, then redacts or blocks them the moment they appear.

Frequently asked questions

Questions on marketplace moderation.

Lasso moderates listings and messages in 200+ languages, with custom banned-item and word lists per language. Slang, transliteration, and mixed-language text run against normalized variants, so the same rules apply whether a seller writes in English, Dutch, or a mix of both. In the moderator review queue, each flagged item appears translated beside the original, so your team can act without reading the source language.

Lasso scans the title, description, and every image in a listing. It catches counterfeits from brand cues, replica language, and image matching, and prohibited items from your banned-item lists per category, covering weapons, drugs, regulated goods, and anything off-policy. A flagged listing can be held before it goes live, removed, or routed to your team, and the thresholds stay configurable per category.

Yes. Lasso detects contact details and off-platform pushes in listings and messages: phone numbers, email addresses, payment handles, social handles, and links, including ones hidden inside images through OCR. You decide whether a match is redacted, blocked, or sent to review, so a 'let's finish this on WhatsApp' message can be caught before the transaction leaves your marketplace.

Lasso flags the patterns fraud relies on: advance-fee bait, fake payment confirmations, account-recovery cons, and pushes to pay outside the platform. These run in buyer-seller messages and in listing text, scored on content and account signals together, so a new account posting the same scam across categories is caught on first sight and filtered everywhere it appears.

Yes. Lasso detects phone numbers, email addresses, home addresses, payment handles, and QR codes, in listing text, in messages, and inside images through OCR. The same scan covers a number typed into a description and one screenshotted into a listing photo. You set whether a match is redacted, blocked, or sent to review.

Yes. Electronics, fashion, health, and ticketing can each carry their own banned-item lists, severity thresholds, and escalation routes, all on one account. A regulated category can run stricter than general goods, or the reverse. Region-specific overlays sit on top, so one category can apply different rules by market.

Default rule sets go live on day 1, so moderation runs from the moment you connect. Custom models train on your labeled listing and message data within two weeks, tuned to the categories, brands, and fraud patterns specific to your marketplace.

Pricing scales with your volume of listings and messages. As your marketplace grows, pricing grows with it. Tell us your numbers and we size it from there.

Lasso gives you the records these regulations ask for. It logs every moderation decision and produces transparency reports on each action, which map to DSA obligations for online marketplaces. For GDPR, Lasso fulfils data export and deletion requests. CSAM matches route to the NCMEC CyberTipline. The tooling supports your compliance; your team owns the policy.

Grow your marketplace, protect your brand.

Send us a sample of your listings or messages. We'll moderate it through the pipeline and walk you through the dashboard.
