Case Study: an EU-based company stops review fraud with FingerprintJS

How one company stopped review fraud with FingerprintJS

An EU-based company operating a popular peer-to-peer marketplace across Europe was struggling with fake reviews. Vendors were using VPNs and clearing cookies to conceal their identities and post multiple fraudulent reviews to inflate their ratings. They turned to FingerprintJS to find a solution that could accurately identify returning visitors despite these concealment methods.

Using FingerprintJS Pro's visitor identification API, the company implemented a system to block reviews from devices that had already reviewed a specific service. This solution allowed them to catch an additional 500 fake reviews per day, drastically improving the integrity of their platform. The company plans to use FingerprintJS for other fraud prevention use cases in the future.
