Last banwave I managed to sell my last gold and then "boom" banned. This time I avoided banwave, but only because I got permabanned the week before XD. However I still managed to sell all my gold just before the banwave. I must be the luckiest gold seller ever. And I'm not being sarcastic.
Not sure how Blizzard investigators work. I was mailing thousands of herbs on daily basis to one character only who was selling both herbs on the AH and gold to other players. That account is still untouched. But I did not attach HB to it as it was only used for manual selling. HB is indeed detected as I don't think Blizzard investigators went that far as they didn't detect my big seller nor cared about where thousands of Fjarn and Starlight per day from my bots ended up. That seller even dominated the AH and on top of that was selling cheap herbs to returning customers for hundreds of thousand gold per day.
It seems like they don't really care about the economy, just getting rid of the bots.
