Several people got banned for botting since the patch. If they can detect the bot(exiled bot I suppose, exilebuddy is down for maintenance luckily), they can detect poe hud as well. It would seem like a better plan to gradually investigate "flagged" accounts and prepare a bigger banwave, rather than auto ban all minor offenders like people who used a zoomhack. I would understand why GGG would decide to instantly ban bots to be their priority, since bots are the ones ruining the economy and actually NOT playing the game.
