This sort of complaint happens every time someone breaks new ground in multiboxing accomplishments. What's odd to me is that these arguments keep coming up, seemingly ignoring the evidence that Blizzard can absolutely fix exploits in a matter of hours when they see things they don't like. (See: high-ROI farm spots, BOE raid trash farms, world boss leashing, aggro bugout mechanics, well-known stand-still-farm spots, etc.) I think I've heard similar plots at least a dozen times in different forms specifically related to multiboxing e.g. "If multiboxers do X, they'll ban us all!" I've been multiboxing in one form or another *in WoW* for the better part of 13 years, and I've never received a ban, suspension, or even an unkind word from a GM. I'd be very surprised to see anything different in the near future.
