Protect your classifieds marketplace from repeat abuse.

A convincing listing or established account can be the beginning of a scam. Once users move into a conversation or an off-platform payment, your team may have less visibility. Kairal helps you examine the registrations, access requests and linked activity that can precede that harm.

Why scammers target classifieds marketplaces

Property, vehicle and job listings connect people who need to make decisions with limited information. Scammers exploit that trust through repeated registrations, automated posting and messages that redirect users elsewhere.

Contact details are valuable too. Bots can collect them for spam or phishing, while compromised lister accounts lend an existing reputation to new abuse. Removing one account leaves the question of related activity unresolved.

The true cost of abuse in classifieds

Users who lose money or receive unwanted messages may blame the platform that introduced them to the other party. Listers can become reluctant to share contact details or return with another advertisement.

Your moderation team spends time removing accounts, reviewing reports and recognising returning patterns. Repeated manual investigations leave less capacity for difficult cases, particularly when each new email address appears to represent an unrelated user.

How Kairal protects your marketplace’s interactions

Kairal assesses automated requests around login, posting, contact reveal and messaging. Session linking helps connect activity across sender or poster accounts; Kairal Business Defense (currently in early access) adds sign-up and posting risk assessment.

This gives moderation teams additional context when prioritising suspicious registrations and repeated attempts. Rate controls can target abusive request patterns at protected endpoints. Events and Sessions support investigation alongside your existing processes for checking listing content, verifying users and responding to reports.

The Kairal advantage: before and after

Consider a team trying to understand whether newly reported accounts are connected:

Classifieds marketplace use cases

Scam listings at scale

Scam adverts can raise fraud-related report volumes and moderation costs while reducing retention among genuine listers.

Contact and lead harvesting

Contact harvesting can raise lister churn rates and contact-misuse report volumes while reducing the qualified enquiry rate.

Messaging spam and phishing

Messaging spam can depress reply rates and increase abuse reports, while repeated sender investigations raise the cost of keeping conversations useful.

Account takeover of verified listers

Takeover of a verified lister can increase affected listing counts and account-recovery tickets while extending the time needed to restore legitimate access.

Ban evasion and re-registration

Returning restricted operators can raise the repeat-offender rate and moderation costs, while broad exclusions increase the burden of legitimate appeals.

Full-catalogue scraping

Full-catalogue scraping increases catalogue serving costs and can divert enquiry volume, while stale copies create listing-accuracy complaints for your team.
