Image-based sexual abuse (IBSA), like other forms of technology-facilitated abuse, is a growing threat to people's digital safety. Attacks include unwanted solicitations for sexually explicit images, extorting people under threat of leaking their images, or purposefully leaking images to enact revenge or exert control. In this paper, we explore how people seek and receive help for IBSA on social media. Specifically, we identify over 100,000 Reddit posts that engage relationship and advice communities for help related to IBSA. We draw on a stratified sample of 261 posts to qualitatively examine how various types of IBSA unfold, including the mapping of gender, relationship dynamics, and technology involvement to different types of IBSA. We also explore the support needs of victim-survivors experiencing IBSA and how communities help victim-survivors navigate their abuse through technical, emotional, and relationship advice. Finally, we highlight sociotechnical gaps in connecting victim-survivors with important care, regardless of whom they turn to for help.

翻译：基于图像的性虐待（IBSA）与其他技术助长的虐待形式一样，正日益威胁着人们的数字安全。此类攻击包括未经请求的色情图像索取、以泄露图像为威胁进行勒索，或故意泄露图像以实施报复或施加控制。本文探讨了人们如何在社交媒体上就IBSA寻求和获得帮助。具体而言，我们识别了超过10万篇涉及人际关系与建议社区的Reddit帖子，这些帖子旨在寻求与IBSA相关的帮助。通过对261篇帖子进行分层抽样，我们定性研究了各类IBSA事件的发展过程，包括将性别、关系动态和技术参与映射到不同类型的IBSA。我们还探讨了IBSA受害幸存者的支持需求，以及社区如何通过技术、情感和关系建议帮助受害幸存者应对其遭受的虐待。最后，我们指出了在连接受害幸存者与关键关怀方面存在的社会技术鸿沟，无论他们向谁寻求帮助。
