Chess.com's User Agreement reserves the right to "prohibit linking to or framing the Services for any reason" and to "suspend or terminate users or reclaim usernames at any time without liability to you". Using a proxy to circumvent a network ban constitutes a direct violation of these terms. Support staff have indicated that while low-level usage might be ignored ("silent compliance"), if an IP is associated with abuse or if the account holder violates Fair Play rules, proxy usage becomes grounds for immediate and permanent termination.
Chess.com issues IP bans to users who violate the site's terms of service, such as engaging in abusive chat behavior, cheating, or creating multiple accounts after a ban. Sometimes, players are also banned unfairly, such as when a shared network connection—like a university dormitory Wi-Fi—has been flagged for prior abuse by another resident. A proxy or VPN can mask the original IP address, allowing a banned user to create a new account and regain access. However, Chess.com actively tracks browser fingerprints, device information, and playing behavior patterns, so changing your IP address alone may not be enough.
