An important thing to keep in mind is that we don't make public announcements every time we action players for cheating, and the reason for this is that we are constantly removing this kind of exploitative behavior from the game -- on a weekly basis, sometimes even on daily basis. Public announcements would become tedious if we decided to make one every single time we banned someone for using a bot, a hack, or some other kind of cheat. Instead, we usually will post something whenever we issue a big wave, or whenever we feel like we need to remind players that exploitative behavior is not okay
and can lead to a permanent ban from Diablo III.
It's something we take very seriously, though. Our developers, support staff, and anti-hack teams are all busting their butts to ensure that your online experience is as free of cheats, hacks, and bots as possible. From the development side, we look at ways to reduce the effects of exploitative behavior on the community and/or prevent certain programs from working outright. This trick here is to make sure that whatever we do doesn't negatively impact legitimate players, which is actually a very fine tightrope to walk (you saw the complications of that whenever we introduced game limiting). From the support side, we make sure that your in-game reports reach our anti-hacks teams. And from the anti-hack side, we take action on players that we are able to confirm to be maliciously exploiting the game, be it through botting or other forms of cheating.
The reality to all of this, though, is that even though we devote considerable time, effort, and heart to removing bad behavior from the game, there will always be individuals who excel at coming up with new ways of getting around the roadblocks we put up. So, it's a constant battle, but one that we're willing to fight. If you want to pitch in, you can; the easiest way to do so is by emailing firstname.lastname@example.org
or submitting a report through our webform
And, just for clarity, let me repeat:
- Exploitative behavior is not okay (this includes botting).
- If you are found to be exploiting the game, you can be permanently banned.
