Recently I came across a post in an Elitist Jerks thread about using AHK in a way that most definitely is not appropriate (think auto-repeater). As "proof" that the use didn't violate Blizzard policies, they actually linked to a thread on this board of one of Keyclone's in-game conversations with a GM saying the critical thing was that you were at the keyboard. Now, I don't have an account to post to that site and I'm pretty sure these recent bans are unrelated to this issue, but it's got to be pretty clear to everyone here that use of delays in macros/scripts is a bad bad idea no matter whether your at the keyboard or down at the pub.
