本研究通过青少年在社交媒体上完成隐私任务时的出声思考，揭示其理解设置的方式，并主张平台应证明保护措施生效且持久。
AI 中文摘要
社交媒体平台已嵌入青少年的日常生活，在支持友谊和身份认同的同时，也使青少年面临不必要的接触和隐私伤害。以往研究记录了注意力捕获策略和暗黑模式如何塑造社交媒体使用，我们在此基础上进一步研究那些表面上提供隐私和安全保护的平台设置。我们报告了与11名14至17岁青少年进行的出声思考会话，他们在Instagram、TikTok、Snapchat和YouTube上完成了六项隐私与安全任务。我们展示了参与者如何通过日常习惯、边界和先前经验来理解某项设置的含义，如何适应比预期更柔和、更不可预测的保护措施，以及如何将平台视为保护应有样子的权威。我们认为，逐项功能评估无法确定青少年是否受到保护，平台应承担证明保护措施已生效且持久有效的责任。
英文摘要
Social media platforms are embedded in teenagers' daily lives, supporting friendship and identity while exposing teenagers to unwanted contact and privacy harms. Previous scholarship has documented how attention capture strategies and dark patterns shape social media use, and we extend this work to better understand platform settings that ostensibly provide privacy and safety protection. We report on think-aloud sessions with 11 teenagers aged 14 to 17 who completed six privacy and safety tasks on Instagram, TikTok, Snapchat, and YouTube. We show how participants worked out what a setting meant through their routines, boundaries, and prior experiences, how they accommodated protections softer and less predictable than expected, and how they treated the platform as the authority on what protection should look like. We argue that feature-by-feature evaluation cannot establish whether teenagers are protected, and that platforms should carry the obligation to show that a protective action took effect and is durable.
