Well, one of my accounts banned was a mule I had just created and NEVER used except to transfer a couple of items. After that I just "burned" the character in while I went and did other things, occasionly checking to see if I timed out. After I was sure a couple of hours went by I logged out and had not touched it. To me this is 110% proof that the banning was done in to send a message to users and not too fix anything.
