So I have taken up the habit that many here have shared with me. I now camp the various WoW Official Forums looking for chances to defend the honor of multiboxing. I ran across this thread. Now, we're not botters - we're HACKERS. I think I preferred being called a botter better. Well, maybe not. But you know what I mean...

The OP backed off the 'HACKERS ZOMG' nonsense immediately, and then went back to the 'botting' nonsense. Belfaire took care of that one pretty quickly.

Botting. You keep using that word. I do not think it means what you think it means.
Golden. More from Belfaire.

He's still in direct control of each account.
Even more golden. And later...

The software can't control the characters. He has to press a button. If you want to get into semantics, you're not controlling the character, your keyboard is.
ZOMG!!!!111!! Exactly what we say. Will people take it seriously now that a blue spells it out? The OP says:

If they were winning the arena tournament you wouldn't be saying this, they would get banned, because letting people do this in an es-port is laughable and any other serious game would have banned them long ago.
Damn. Well, I can dream, can't I? Oh, and notice the old myth rearing its ugly head again - he's assuming that MBing is a new trend that no one tolerates EVER in the history of gaming.

Oh, and as a side note, the multiboxer in question is Aelli. Of course, in an arena QQ, we would expect that by now.
