Because my server is failboating right now, I figured I'd add some additional logic to this post.

1) Blizzard can ban you for sneezing the wrong way. It's true. I'd like to think that they're a benevolent diety, though. So, since they define the "spirit of the game" they can ban anything they want.
2) Blizzard has made it clear that bots are not inline with the spirit of the game. I think we all agree on that.
3) Innerspace is associated with a botting program that is currently in a legal mess with Blizzard. Innerspace is also associated with other scripts that only run and were written FOR the Innerspace platform and whose sole purpose is to bot.
POINT A: Innerspace has the capability of being a platform for bots.
4) You do not need to be involved in a legal mess in order to get banned from WoW. Glider users were banned LONG before the lawsuit. Other bots were never involved in legal software and were also banned.
POINT B: A program does not have to have a legal struggle with Blizzard in order to be bannable from WoW
5) From Lax's description, Innerspace either reads or resides within WoW's memory.
6) From the precedent currently being made by the legal squabble between MDY (Glider) and Blizzard, programs that futz with WoW as it resides in memory are making illegal copies/alterations of WoW that are not covered in the licence/terms. This is gray area as the legal battle is not complete.
POINT C: Fussing with WoW as it resides in memory is gray area
7) Innerspace, as a name, is highly associated with botting programs.
8) Multiboxers, as a community, are often misassociated with botters. Multiboxers, in general, would prefer that this no longer happens.

... you see where I'm going here?
