Has the bot changed since the banwave? precautions taken by staff?

Is the bot safe after the banwave? I know botting is never safe, but as a long time botter who botted 20 chars on my current account and still havent got banned I worry. I just came back to WoW and have rerolled server so its time to bot again. But seeing that the reason for the banwave against HB is unknown I wonder if its "safe" They obviously hardware detect HB now, so will it all be about luck? About not having HB running when they scan for it? Have the staff "fixed" it?
