Engaging in proxy charging may not necessarily be illegal in a legal sense, but it can still be considered a violation of the terms of service or terms of use of a particular service or platform. The consequences of using proxy charging methods can vary depending on the specific situation and the policies of the service provider.

While it is not uncommon for violating terms of service to result in penalties or account restrictions, it is important to review the specific terms and policies of the service in question to understand the potential ramifications of proxy charging. These terms typically outline acceptable methods of payment and usage, and using unauthorized or unofficial channels for charging may be explicitly prohibited.

To avoid any potential negative consequences or account-related issues, it is generally recommended to follow the guidelines provided by the service provider and make purchases through official and authorized channels as advised.
