As far as I remember the day blizz announced the 3month bans for xxxx amount of players there were only couple of people who got the suspension using the hearthbuddy. However, at the same time heartcrawler (another botting software from another developer) got shitloads of banstorm that even their web went down and they basically said "Screw you guys we are going home" - Cartman style, and left all those who purchased that software with empty hands. So far so good, buddy the best!
