Be sure to pay attention to the security issues of Using proxy servers

When using the proxy server, all your operations may be recorded, including time, routing, various applications, user IDs, passwords, and so on, which may lead to secret leaks. You are safe for other users and servers on the Internet, but you are at a glance for the proxy server itself! The Administrator of the proxy server or someone who has administrative permissions on the proxy server through other means can easily possess your secrets! Therefore, do not use the proxy server to send and receive emails involving personal privacy and institutional secrets; do not use the proxy server for illegal activities; do not use the Proxy Server FTP or perform other operations that require providing the user ID and password!
