Hello,
About HB, sincerely, without the contents created by the HB community (profiles, fight classes, plugin, ...), HB is an very basic bot, the dev team take few days to release update after new wow update (I have never understand why, security is false pretext, you can see result...) (I work alone, it takes me a few hours for normal update, and we can begin to work on the PTR server for beings ready when build is released on live server). After the banwave a few months ago, HB team have reopened the bot without knowing exactly what had caused the banwave, current banwave is a logical continuation... This is not the first fault, I was already here at the time where bossland began to writte bot with GatherBuddy, after few months it had already taken a banwave (because poorly coded). Even the banwave dating from there are 1 or 2 years old could be avoid because they had was warned that bliz had added a detection method.
About WRobot I have worked hard to make wrobot hard to detect (it is more easy to detect HB that WRobot (If any have knowbase he can test)), I use a special technique that I have not seen on another bots to hide WRobot in memory. I know what I'm doing (if I worked among bliz, the bots would have disappeared ^^). I cannot say that WRobot is undetectable (all is detectable), but I work to avoid it, and I think WRobot is among the most secure bots.
ps: Sorry for my English.
