While I take pains to make sure few people see me multiboxing (instance runs most of the time, questing separately or at odd hours, etc) some people do figure it out. Almost all of them have had positive things to say to me. They will ask "are you controlling all of them?" because they see this group with the same guild tag and similar names standing somewhere. And when I say yes most of them will reply "haha that's awesome" or "lol that's pretty cool." One person told me he had tried dual boxing and I think that seeing my little army run around had gotten him to think of trying it again.

Then again I do not have any of the general chat channels open, because on my server they are filled with 99% useless stupid crap. It's like a 24/7 retard convention. So if there are people calling me out in public chat channels, I don't see it. It probably doesn't happen because usually when they start up in chat, someone eventually whispers you to ask if you can see what they're saying about you, and I've never had that happen. But again, I stay off of people's radar. My guildmates know that I multibox, and while one of them doesn't seem to like it, he admits that he's impressed. The rest think it's pretty cool and they joke about it whenever I'm on. Someone will log in and say "wow, lots of people on tonight." Then someone else responds "not really, 18 of them are Tonuss."
