From what I gather, this is basically a proxy service.

We do not directly have anything against such services (we have no preference as to which route you take in order to connect to our servers). However, proxies are routinely used to hide the actions of online trading companies and users attempting to use exploitative third party programs. We neither condone nor prohibit the use of proxy services for legitimate purposes, but please always remember that you will do so at your own risk.

This is exactly what I would have said if Ellifara had not beaten me to it Arïel. While our programmers are constantly improving Warden and the detection methods it uses, we cannot guarantee that 3rd party programs such as this will not conflict. It’s not something we can support and therefore using them is entirely at your own risk.

As you have discovered, we will do our best to ensure that any undeserved account actions are swiftly removed, but the potential for inconvenience is something you need to accept if you are going to run programs such as this.

We have no official stance on tunneling services, as they are not officially supported or forbidden. They are basically use-at-your-own risk, as they are external to the World of Warcraft client. There have been reports that due to various factors accounts may be security locked when a tunneling service is used. In cases like this, please contact an Account Services Representative for assistance.

Please keep in mind that using such services can potentially open your computer to new risks, depending on how that service is handled, so make sure to research these solutions thoroughly.

We understand that some people are using proxy or ‘tunneling’ services as a way to overcome latency issues; generally because their ISP may not be taking the best and fastest route possible to our servers.

Using these services is not now, nor has it ever, been a violation of our Terms of Use. Simply using a proxy is not enough to cause us to take action on your account. But! they’re not officially supported either.

The reason why use of a proxy can be an issue is that the majority of organizations that abuse the game use proxies themselves. While we work to detect and stop these activities, we also work to prevent any ‘false positive’ results; but they do sometimes occur. Our false positive percentage is minuscule in relation to the number of accounts actually found in true violation of our policies, but they can happen. We work as fast as possible to review these cases and get our legitimate players back in the game.

If you do use, or want to use, a proxy/tunneling service, you can help prevent the likelihood of becoming a false positive by using the proxy service consistently.

We’re continually improving our abilities to detect those that violate our policies, and with that we’re continually improving our ability to more accurately identify (or rather, not identify) those that are using proxies legitimately.
