This is interesting, as it brings up the obsession a lot of solo boxers have and hate about multiboxers. They can't get over the idea that they're facing one human player, regardless of accounts. Daoc was like that -- you'd play a single human, but he was buffed by an account that you couldn't attack in a safe zone, so effectively wasn't there -- hence the bad feelings about buff bots. There were still plenty of multiboxers on classic servers, but no one cared there.

It seems to me to be against the kind of premise of a multiboxer, which is to view everything as accounts not people -- and to master running those accounts as much as if you were individual humans as possible, making sure that nothing you do is outside the bounds of what a legitimate human player could do.
