Case Studies
The TSF Case Studies are a series of real-life examples of trust and safety issues. Each case study demonstrates how difficult it is to make trust and safety decisions and discusses the trade-offs inherent in each decision or setup, prompting readers to think about the questions raised by the case study and consider the implications and outcomes.
These case studies may be helpful as a training tool as they examine past examples that resonate with current challenges. TSF publishes case studies in an effort to form an ongoing repository of trust and safety examples providing deeper insight for the broader public.
The case studies are written by TSF staff, volunteer and paid writers, and The Copia Institute.
