sorry where exactly... what did you look at in blockexplorer to deduce this?
IBB posted a payback URL when I was looking at the thread last night. It showed a payment of 7 bitcoins to it 9/17, and a subsequent moving (selling?) of those bitcoin an hour later. It seems like the IBB removed that post, so I'm hesitant to link it, although I have it in my history and just looked at it again to be sure.
