Short description

Following “Intro to trust & safety”, this session will concern more advanced trust & safety design problems. We’ll also look at the current edge of research and recent product experiments and discuss their implications.


In “Intro to Trust & Safety” earlier, we learned about how to identify and prevent the most common types of abuse vectors. In this session, we’ll take a deeper dive into more advanced best practices and current topics in the field. Specifically, we will look at research, features, and outcomes that we’ve seen so far that have shaped our decision-making today. Then, we’ll tour a selection of user stories to illustrate currently unsolved problems. As a warning, this session will discuss domestic violence and various topics related to online harassment.

Key takeaway

Trust & safety is an evolving field with active research. Attendees will get a tour of the current state and consider some advanced user stories.
