I see a lot of fuss about this exploiting, but what has been happening? Seeing as I've been casually doing arena, I'm getting worried if random people get banhammered. What's been happening? When someone mentions wintrading I always imagine some friends on skype queueing up at the same time and hoping they meet each other, but from the blue's messages it seems there's more going on?
@OP, hope you get your account restored.
Edit: Rite, I googled some. Er, I hope I'm ok, I can see how you can do one accidentally. I tend to ragequit.
