Mainstream platforms' content moderation systems typically employ generalized "one-size-fits-all" approaches, intended to serve both general and marginalized users. Thus, transgender people must often create their own technologies and moderation systems to meet their specific needs. In our interview study of transgender technology creators (n=115), we found that creators face issues of transphobic abuse and disproportionate content moderation. Trans tech creators address these issues by carefully moderating and vetting their userbases, centering trans contexts in content moderation systems, and employing collective governance and community models. Based on these findings, we argue that trans tech creators' approaches to moderation offer important insights into how to better design for trans users, and ultimately, marginalized users in the larger platform ecology. We introduce the concept of trans-centered moderation - content moderation that reviews and successfully vets transphobic users, appoints trans moderators to effectively moderate trans contexts, considers the limitations and constraints of technology for addressing social challenges, and employs collective governance and community models. Trans-centered moderation can help to improve platform design for trans users while reducing the harm faced by trans people and marginalized users more broadly.
