Marketplaces grow by reducing friction: faster onboarding, instant orders, frictionless transactions. But every layer of friction you remove is also a control lever you sacrifice, and that’s the opening fraudsters exploit. 

Fake sellers and fraudulent listings lead to buyer complaints and erode their confidence. Account takeovers expose users to financial loss and trigger costly disputes. Payment fraud drives chargebacks that eat directly into margins. And promo abuse inflates customer acquisition costs while delivering zero real growth. 

The damage compounds in remediation: manual review queues grow, conversion drops as friction increases to control risk, and users - both buyers and service providers - quietly leave for platforms that feel safer.

From chargeback losses and operational drain to conversion drop-offs and reputational damage, we’ll look at the measurable and hidden costs of fraud and overly strict controls.

We’ll share actionable recommendations from experts in the industry on scalable fraud prevention and verification workflows that protect revenue without slowing platform growth.
