only game (to my knowledge) ever having a ban against multiboxing was very early everquest (the ultimate multibox game haha) but after awhile they removed it because it made no sense.

How would you ban ppl, on what grounds, what proof would be considered enough, and lastly no company could afford the amount of GMs required to track multiboxers since they follow the same patterns normal player does.

The difference on botting is that you can track it by searching for repetitious patterns etc, and lastly multiboxing make use of core fundamental functions that have been around in IT since the 60s, it would come down to "haz pc must be multiboxer" ie most of us who plays.

And lastly, and this is where Blizzard got alot of heat, tracking program like warden(wow) would have to be allowed to act the same way as keyloggers and trojans in order to really see if you are using a program that allows you to run several clients at the same time. Warden is "only" allowed to track its own memory space, which is still considered "blizzard" property.

So while a multiboxer might annoy the odd player in an mmo much like a fly annoys an elephant the resources required to hunt down ppl who multibox are atm being used by NA to hunt terrorrists, so untill that problem is solved or multiboxing becomes no1 prio of the NSA, dont bother
