Given the questions sent to each company, the responses are exactly what I would expect.

Correct me if I'm wrong, but the questions to the companies were:
"Do you allow Hardware multi-boxing?"
"Do you allow Software multi-boxing?"

Why would there be so many different responses? Because there is no description in the question as to what multi-boxing is. Sure, just about everyone here reading these forums understands what is meant, but the average person playing and even support personnel of the games aren't always going to know what is meant by those terms. To the average person playing an MMORPG, multi-boxing means botting. Just about everyone I see unless they know what it is about and know it's legal, will first say "oh, a bot!"

I'm willing to bet that if a description went along with the question as to what multi-boxing is, you would have received different responses. Most of them indicating it was OK to do. If they understand that a person is at the keyboard controlling the characters by pressing a key that is sent to all instances of the game and is not automated game play, they would have said it would be allowed. If you just ask, do you allow multi-boxing, how do you know the person that is answering understands what it is you're asking?
