The researchers found that a substantial number of YouTube channels repurpose their content and identity, sometimes after being sold in online marketplaces. About a quarter of repurposed, sold channels disseminated potentially problematic content, often without being penalized by the platform. Handle changes, upload frequency, and the time since the first video are potential indicators of channel repurposing.

This is a solid study with a clever approach to exploring channel repurposing on YouTube. The methodology is generally sound and utilizes multiple data sources for analysis. While there are limitations, such as reliance on metadata and restriction to a single platform, the findings are valuable and the innovative use of LLMs for analysis is commendable. The combination of quantitative and qualitative approaches strengthens the research. The lack of access to full video content does limit analysis of actual harm.
