Team Description

Ad Safety is a growing team focusing on user safety and advertiser trust by building a robust, automated ecosystem that prioritizes Brand Suitability and Ads Integrity. This is achieved by deploying highly accurate automated ad review systems that vet content before it goes live, coupled with advanced brand safety classifications and controls that give brands granular agency over their ad adjacency along with ensuring Reddit standards are adhered to. By further integrating with trusted third-party verification partners, the platform not only solidifies confidence in its ad effectiveness but also creates a transparent, scalable environment designed to unlock significant revenue growth.

The team is expanding its Fraud counter-measures by consolidating the identification and enforcement of deceptive ads (Malware, Phishing, Scams) and Billing fraud into a centralized platform.
