I'm 90% sure thats whats causing several of the bans. I updated my graphics driver after playing all day. 15 minutes later I log back in and get banned 10 minutes into it. What a great product: Hey you! Want better D2 performance?? Come download this driver update. You'll get banned for doing it but hey those 10 minutes youll have 5 more frames per second.. complete joke. Bungie needs to address this now.
