Yesterday, while doing my daily bot routine I noticed HB had an update. I update my bots then launched them and noticed something peculiar, it was sending a few of those [Blahblahblah] messages from the HB log to the center of each wow's screen... I figure they did this buy LUA or something similar and if so blizzard could have easily tracked it down. This was about the only change in HB on tuesday and is about my best guess of what happened.
R.I.P to all the botting accounts (for 6 months >.>)
