Reddit 正用 AI 对抗 AI 垃圾信息

reddit has rolled out new internal tools powered by large language models to combat the surge in ai-generated spam, successfully blocking 23 million spam views and 25,000 malicious posts daily. by leveraging llms, the platform claims to detect 'coordinated patterns of fake behavior' that older automated systems failed to catch, resulting in a 20% drop in user exposure to spam between january and march. this strategy reflects a broader industry pivot, as platforms like meta and youtube struggle to moderate the ai-generated content their own policies often permit. while automated detection improves speed, experts maintain that these systems must still rely on human moderation to effectively manage hate speech and complex policy violations.
