Lastly, this is a good time to remind the community of a few things:
Third party addons of any kind are strictly prohibited. While any kind of botting software falls clearly under violation of our Terms of Service, for Diablo III, this also includes any kind of overlay software, map hacks, or any other addons or alterations to the client. Addons are not supported for Diablo III and use of them may result in account warnings or permanent account closure.
We are committed to continuing to support Diablo III, including taking action against botting and cheating. Please keep in mind that we do routine actions to keep Sanctuary fair for everyone, and we will not regularly provide public notice of mass account actions.
So yes, there was a recent official stance made. While they didn’t name anything in that post, TurboHud is an overlay with a map hack. And was named below:
That was provided by one of the game producers. Note the words “In its current state”. This is referring to the fact that it provides advance knowledge of pylons, elite packs, etc, and shows approximately twice as much of the map ahead of you than the in-game map does.
