Well over 1000 people seem to have gotten banned today. We have been looking hard for signs of detection and using the bot ourselves since there were a few bans last week. So far we have not found anything and the development accounts are not banned. As of now, this looks like a server side detection of a behaviour pattern. Both the EU and US Official Diablo 3 forums are full of angry banned players. In our experience botters take their bans and move on without grumbling. We think perhaps the server side algorithm hit a lot of innocents as well. In the interests of safety, we have disabled Demonbuddy auth and are going to review our options tomorrow.
