Have they found how the caught them?

Hello and sorry if this is an old info...I got banned in the banwave for 6 months. I was botting for 4+ years in my account with no issue. In 3 months the ban is ending and will play again. I remember bossland said that they don't know how they got them..did they found out? Is honorbuddy "safe" again? I mean if they managed to counter the way Blizz found them... I understand it will never get safe, just if the risk is as was before the banwave, where someone had to report you and so on... I only use bot for rotations, so in order to get me, it need to be detectable..
