AI 中文总结
该研究分析“X”平台超1300万用户数据，发现安全隐私讨论多集中于兴趣社区，核心贡献是揭示社交网络安全隐私讨论的信息茧房问题并提出扩大覆盖的思路。
AI 中文摘要
安全与隐私方面的教育和指导的传播过去是、现在仍然是一项挑战。社交网络是分享最佳实践的潜在途径，实验表明它们在这项任务上是有效的。尽管这看起来很有前景，但在现实世界中，安全与隐私讨论需要覆盖广泛人群才能发挥效用，而要避免常见的“信息茧房”。我们试图理解围绕安全与隐私讨论的社区如何运作，重点关注需要克服哪些挑战，才能让安全与隐私讨论和建议触达更广泛受众。我们发现，社交网络中真实的安全与隐私讨论场景与实验环境呈现出截然不同的情况。我们构建并分析了一个包含“X”平台（前身为“Twitter”）上超过1300万用户的图结构，其中包括10159名发布安全与隐私相关内容的用户及其粉丝。此前研究表明，如果志同道合的社交关系已对社交媒体上的信息进行了可见互动，用户更有可能考虑该信息。我们的研究结果表明，生成或参与安全讨论的用户大多已属于高度聚集的技术、安全及隐私相关兴趣社区，这意味着那些未处于相关兴趣“核心圈”的人可能无法有效接触到这些讨论。我们最后就如何扩大社交网络中安全与隐私指导的覆盖范围提出了思考和想法。
英文摘要
The dissemination of security and privacy education and guidance has been and still remains a challenge today. Social networks represent a potential avenue for sharing best practices, and experimentally they have been found to be effective at this task. While this appears promising, in the real world, security and privacy discussions would need to reach a wide range of people to be effective, avoiding the "interest bubbles" that commonly occur. We sought to understand how the communities surrounding security and privacy discourse operate, with a focus on what challenges need to be overcome to enable security and privacy discourse and advice to reach a wider audience. Indeed, we found that in-the-wild security and privacy discussions in social networks portray quite a different picture than in experimental settings. We built and analyzed the structure of a graph containing over 13 million users on the "X" platform (formerly "Twitter"), including 10,159 users who posted about security and privacy and their followers. Prior work has shown that users are more likely to consider information within social media if their like-minded social ties have visibly engaged with it. Our findings indicate that the users generating or participating in security discussions largely already belong to highly clustered technology and security- and privacy-related interest communities, which suggests that the people who are not already in the "inner circle" of relevant interests are likely not exposed effectively to these discussions. We conclude with reflections and ideas on increasing the reach of security and privacy guidance in social networks.
