An international study led by Universidad Politécnica de Madrid found that 58.7% of custom ChatGPT assistants violate OpenAI's usage policies, enabling academic fraud, forming inappropriate romantic relationships, and providing sensitive cybersecurity instructions. The findings highlight significant moderation challenges and led to the removal of some offending assistants from the GPT Store.
