Hey there Jsvysjc,
The question here is an interesting one and I can understand why there is confusion regarding the responses given. Most of what is needed to know about this has already been said but I figured my response may help put this to rest with as much clarification as possible.
Multiboxing, or playing more than a single World of Warcraft account at once is not a direct violation of the End User License Agreement. Programs that copy key presses or in any way mirror button presses to multiple accounts is however. This also includes software or hardware that automate or streamline multiboxing. Our general policy on this is found here.
We made public announcement regarding this change on our website. Later on, we made another post on the forums regarding this here.
The title of the thread here does mention software. I then see it mentioned that a friend is using a different input device on the same system to control, and thus not actually mirror what the keyboard is doing. This is a grey area and one that, frankly, few in Customer Support would be able to directly answer without the vagueness that was already expressed in the thread here and by other Game Masters.
When a question like this comes up that’s in that grey area, the overall thought is to still error on the side of “don’t do it”. Debating the mechanics of what’s being done will not change that it’s a risk to do so. This means if it’s not a clear yes or no, it’s best to just not do it. The last update you received also states this while also reiterating on the policies already mentioned.
Which brings me to the last part which is this is more of a general discussion and feedback more than a technical one. Additionally little has been added with each reply and I’m afraid on my end I can only repeat the information you’ve already seen. While we encourage discussion and feedback, the technical support forums are for troubleshooting game problems, not discussion of account actions or how to interpret the EULA. I’m going to lock the thread. If you want to share constructive feedback about the policy, please do so in the appropriate place.
