社交媒体公司正在升级技术手段来识别平台上的儿童用户。Meta作为行业先锋，在与美国48个州及哥伦比亚特区达成的180亿美元和解协议中做出承诺，将在一年内完善年龄验证方法1。该公司计划利用人工智能分析用户的发帖内容、互动模式、朋友关系及登录时间等多个维度来识别未成年账户1。
其他主要平台也在推进类似举措。谷歌YouTube采用AI技术根据用户观看历史来区分成人和未成年人1，而Roblox则要求玩家上传视频自拍进行年龄估算，声称对5-25岁人群的准确度在正负1-2岁范围内1。
这些技术手段面临多方面挑战。电子前沿基金会警告，"互联网年龄门槛化"可能侵犯言论自由和隐私权1。此外，谷歌拒绝了让应用商店负责年龄验证的建议，指出这种方式无法覆盖桌面和共享设备1。
Social media platforms are strengthening their ability to identify child users through advanced age verification systems, driven partly by regulatory pressure and legal settlements. Meta agreed to enhance age verification methods as part of a $1.8 billion settlement with 48 U.S. states and the District of Columbia, committing to refine these techniques within one year.1 The company's approach relies on artificial intelligence that analyzes multiple user behaviors—including post content, friend relationships, and login patterns—to identify underage accounts.1
Other major platforms are pursuing similar strategies. Google's YouTube employs AI to distinguish adult from underage users based on viewing history,1 while Roblox requires players to upload video selfies for age estimation, claiming accuracy within plus or minus one to two years for users ages five to twenty-five.1 TikTok is also among the companies upgrading comparable measures.1 However, these technological efforts face significant pushback. The Electronic Frontier Foundation has warned that widespread age verification could facilitate "internet age-gating" and threaten both free speech and privacy rights.1 Google has rejected proposals to shift age verification responsibility to app stores, noting such an approach cannot address desktop and shared-device usage.1
