Why does everybody 1/10 of this forum ask about banning! The people on the forum sure as hell dont. They find an exploit and share it to make a better game for everyone!
The people that finds exploits DON'T KNOW if you will be banned or not!
You can see it like this:
Error in programming code from the developers side: Hotfix and maybe a rollback, probaly not a ban-reason.
Program that automat things for you = Ban-reason. Autoit etc.
This is clearly an error mistake by some programmers that havent really thought it through enough..When you put auto-it and a spell that is cast over and over, Blizzard might take action but its not likely gonna happen!
