+## Risks
+
+Although the data is publicly accessible, ethical considerations around secondary usage and user expectations remain relevant. 
+GitHub users may not expect their publicly available issue comments or repository discussions to be used for ML and semantic retrieval tasks. 
+The dataset may contain sensitive information unintentionally included by users, such as API keys, authentication tokens, email addresses, internal system details, or confidential technical information.
+In future for greater security purposes, users could consider protecting API key by storing it in the OS environment for safer access.
