There is a bot on the Neutral AH. I knew this day would come. I was trying to transfer some gold to my horde character, so I purchased a black lotus, put it on the Neutral AH, and within 2 seconds, it was purchased by a bank bot with russian characters that I can't type. Attached are some screen shots. Just a heads up.
