A few Innerspace botters did get banned in the "banwave" along with all the Gliders, this is most likely down to the type of Bot they were using and the repetitive nature of said bots. Warden isn't Blizzard's only method of detection, they have server based detection as well (Sentinel) which noone really seems to know very much about at all.

Edit: I take it back, Innerspace did get hit with a banwave.
