Are Private Servers Forbidden?

Q u o t e:
From the EULA:

You shall not:

facilitate, create or maintain any unauthorized connection to the Game or the Service, including without limitation (a) any connection to any unauthorized server that emulates, or attempts to emulate, the Service;

Private servers are "emulating" the service.

***Quoted for Turtle***

I would highly recommend that you steer clear of private servers, Lawl, no matter how appealing the lure may be. They are against the rules, as well as the law; the risks are simply not worth it.
