When users think of emulators, they think of programs like Dosbox or zsnes. These applications run as virtual machines and are slow, having to emulate each processor instruction. Wine does not do any CPU emulation - hence the name "Wine Is Not an Emulator."(http://www.winehq.org)
Some people argue that since Wine introduces an extra layer above the system a Windows application will run slowly. While technically true, Wine is no different from any other software library in this regard; even newer versions of Windows must load extra resources to support older applications.
Not an emulator, sorry dudes.
The most reasonable course of action has already been suggested; have your cadre of banned buddies call customer service and explain the problem. Even if you haven't been banned yet, you can still open a support ticket asking about this; might as well preempt them with your concerns so that if you do get banned, you have some correspondence to back you up.
