I've first seen it on youtube and just thought it was the coolest thing. Before this, I was dual-boxing alt-tabing style on my own.

I was open minded and knew that it could be possible and not a hack, so I looked into it, came here and the rest is history.

If I saw it in-game, I would ask how he/she did it and just learn from it. I wouldn't go around harassing people just because I didn't know how it was done.
