People have tried to ban multiboxing, but it will never happen.
Proof and some arguments :

I do not know the purpose of others multiboxer so I'll only talk about mine, i multibox because it's funny, it's like a challenge for me, because people thinks it's easy to do but it's not, if it was that easy, everyone would do that, people cry because they are jealous. After 6/7 years playing World of Warcraft, it become a bit boring when you play on private server. I don't want to need to make a group to raid citys or to do high level content. I prefere ganking by myself or with another multiboxers. I don't care if i take 5/10/20/50 or 100 slots, it's not my problem.
Multiboxing is allowed, that won't change, i don't need arguments to defend myself. Deal with it.
P.S: Do you know that multiboxing isn't only shamans ?
