It mentions that the platform in question does not support end-to-end encryption for messages, which is crucial for protecting the confidentiality of such discussions. Whether through restricted groups or private messaging, users are advised against using this site for conversations around zero-day vulnerabilities due to the lack of adequate security measures.
