微信公众平台发布新规，严管“非真人自动化创作”，明确禁止利用AI、脚本或接口替代真人创作与发布。违规场景包括完全由AI生成或改写内容、程序托管发布等。平台已开始批量删除被判定为自动化生成的文章，标志着对AI滥用行为的监管进入实操阶段，旨在维护内容生态的原创性。
OpenAI在加拿大枪击案后采取补偿措施，但专家批评其以企业监控替代民主监管。枪手作案前数月，其ChatGPT账号因涉暴力内容被标记并封禁，但问题未得到根本解决。
Meta宣布将用自研AI系统逐步取代第三方人工审核，以应对内容监管挑战。公司认为AI技术已能处理重复性审核任务，未来几年内将在Facebook和Instagram全面推行自动化审核，减少对人工审核的依赖。
快手平台近日发布公告，针对“AI魔改”视频乱象展开专项治理。平台通过技术识别与人工审核，2月处置违规内容4096条，重点打击恶意篡改经典影视动画作品的行为，以落实主体责任，响应相关监管要求。
