Just to be clear, I am not condoning and ever trying to discuss ways to circumvent the account sharing rules.

What I am saying is that it is possible for people that are being quite legal in their actions (eg family grouping together, room/dorm-mates all leveling as a group) while using methods that we advocate people use in the multi-boxing discussions and whether or not that will be differentable by Blizzard or if it will look like someone multiboxing with shared accounts.

It doesn't affect me yet, but it is a situation that could affect someone in this thread based on their description and it could affect me in the future since I have started dating someone that also plays WoW and I will likely drop 1 character from my team to group with her.

The question comes down to if Blizzards tools will be accurate enough in timestamps to know straight away if someone is legit grouping or illegally sharing and how to deal with the situation if they can't.....do we not group with anyone in our house if we usualy multibox?

I guess one way a GM could test would be to just have people do two different things at the same time on the characters they claim they aren't boxing....such as tell one character to go forward and cast/say something while the other character does a circle backwards saying something different at the same time. I'd say no multiboxer could pull that off, no matter the set-up they use.
