A new study by Cornell Tech uncovers the mounting challenges Reddit moderators face due to the surge of AI-generated content. As artificial intelligence tools become more accessible, moderators are grappling with a triple threat affecting the platform’s health and their own experience.
Threats to Content Quality
Reddit relies on volunteer moderators to maintain quality discussions. AI-generated posts can flood subreddits with low-quality or repetitive content, making it harder for users to find valuable information. Moderators now spend more time sorting genuine posts from AI spam, which dilutes meaningful interactions.

Impact on Community Dynamics and Governance
AI content doesn’t just disrupt quality—it threatens the essence of Reddit communities. Automated posts can alter community tone, stifle organic discussions, and introduce misinformation. Moderators must step up governance efforts, but their increasing workload often comes without adequate support from the platform. This imbalance leads to fatigue and questions about the sustainability of volunteer moderation.
In summary, AI-generated content poses significant risks to Reddit’s community-driven model. Addressing these concerns requires better tools, more support, and a renewed focus on the core values that make Reddit unique.
