Meta 推出 AI 工具打击引流至虐童内容的广告
Meta 周三宣布,2026 年上半年在 Facebook 和 Instagram 上对 3320 万条儿童性剥削内容采取了处置,其中超过 97% 由其系统在用户举报前发现;印度同期为 530 万条,98% 以上为主动发现。公司同时上线新的 LLM 系统,用于识别所谓“signposting”——即表面正常、实则把用户导向站外非法内容的广告,判定范围从广告内容扩展到其跳转目的地。Meta 还新增一个“红队 AI 智能体”来测试自身防护的薄弱点,并改进对封号后重新注册账号的识别。
它显示大型平台正把大模型用于广告跳转链路的主动审查,而不只是内容本身,这对内容安全与广告审核的技术路线有参考意义。
Meta announced Wednesday that it took action against 33.2 million pieces of child sexual exploitation content on Facebook and Instagram in the first half of 2026.At the same time, the company is rolling out new AI tools to find ads and accounts that may be used to secretly direct people to illegal child abuse material.
More than 97% of the content Meta acted on was found by its systems before users reported it, the company said. In India, Meta acted on 5.3 million pieces of child sexual exploitation content during the same period, with more than 98% detected before users reported it.
Meta said its latest AI tools are aimed at people using ads that look harmless to send users to illegal content outside Meta’s platforms.
The company has introduced a new large language model (LLM) system to detect what it calls “signposting.” This refers to ads that may look normal but are suspected of directing users to illegal content or other harmful activity elsewhere online. Meta says this is a tactic it has recently seen bad actors use as they continue to change their methods to avoid detection. While the ads themselves may not contain illegal material, they can still act as a gateway to websites hosting child sexual abuse material.
