我们提出了一项关于一组在线服务提供商的信任和安全技术的调查结果，这些在线服务提供商共同为数十亿用户提供服务。我们将要求提供商能够随意访问用户文件和通信内容的技术分类为内容依赖性技术和内容无关性技术。我们发现，更多的供应商使用滥用报告功能（这是内容遗忘）比其他滥用检测技术，但参与者的滥用报告工具并不总是涵盖用户可能遇到的滥用类型。我们还发现，尽管参与提供商之间的强烈共识，自动内容扫描（这是内容依赖）是检测儿童性虐待图像的最有用的手段，他们不认为它是几乎一样有用的其他类型的虐待。这些结果表明，依赖于内容的技术并不构成保护用户免受滥用的银弹。它们还表明，端到端加密（有争议地，它阻碍了外部对用户内容的访问）对滥用检测的影响可能因滥用类型而异。这些发现对在线服务提供商的反滥用义务及其使用端到端加密的监管政策辩论具有影响。
We present the results of a survey about the trust and safety techniques of a group of online service providers that collectively serve billions of users. We classify techniques that require the provider to be able to access the contents of users’ files and communications at will as content dependent, and content oblivious otherwise. We find that more providers use abuse-reporting features (which are content oblivious) than other abuse-detection techniques, but that participants’ abuse-reporting tools do not consistently cover the types of abuse that users may encounter. We also find that, despite strong consensus among participating providers that automated content scanning (which is content dependent) is the most useful means of detecting child sex abuse imagery, they do not consider it to be nearly as useful for other kinds of abuse. These results indicate that content-dependent techniques do not constitute a silver bullet to protect users against abuse. They also demonstrate that the impact of end-to-end encryption (which, controversially, impedes outside access to user content) on abuse detection may vary by abuse type. These findings have implications for policy debates over the regulation of online service providers’ anti-abuse obligations and their use of end-to-end encryption.
