As a field of study, trust and safety is relatively new. The operations and processes that it includes, however, have been in place for many years, dating back to the beginning of networked communications and becoming an increasingly common function within companies as the commercial internet developed. Unlike other fields within the wider world of technology, such as cybersecurity or privacy, trust and safety has lacked an accepted and authoritative glossary of key terms. Glossaries can help with clarifying concepts and definitions. For example, the introduction to the National Institute of Standards and Technology (NIST) Glossary of Key Information Security Terms states: "Over time, use of this Glossary will help standardize terms and definitions used, reducing confusion and the tendency to create unique definitions for different situations" (NIST 2019).The Digital Trust & Safety Partnership (DTSP) brings together providers of diverse digital products and services around a shared framework of best practices for trust and safety (DTSP 2021). 1 As part of our objective of articulating and promoting best practices, we have developed a Trust & Safety Glossary of Terms that professionals use in their dayto-day operations (Digital Trust and Safety Partnership 2023). Whereas other efforts to address trust and safety practices often start from theoretical approaches that are then applied operationally, our approach has been to begin by describing how practitioners understand the terms they use and how this informs their practices. This article unpacks our descriptive approach to developing a trust and safety glossary. We explain the motivations behind assembling a glossary, our method and its limitations, and the challenges we encountered when putting the glossary together. We also discuss how we will proceed from here, as we aim to provide an evolving, increasingly comprehensive but easy to use glossary for different stakeholders.
Why a glossary?Controversy around undesirable online content and conduct, from online harassment to copyright infringement, is not a new issue (ACLU Cyber Liberties Update 1995). In the early days of the internet, trust and safety operations, often conducted by network administrators or volunteers, faced many of these same issues (Dibbell 1994).As a professional function within digital services, trust and safety developed quietly over the course of several decades (Cryst et al. 2021). Since roughly 2004, the rise of social 1. DTSP partner companies are listed at https://dtspartnership.org/.
