Pat1900 got it started. I tried following the change from a few of those transactions forward and found that the zero-fee transactions continue for a while... I found transactions at least up to Feb 16th or 17th. Often these zero-fee ones are finally ended with a fee transaction that looks like it might be a later transfer out. Very hard to follow without some big graphical interface to pan around in.

Anyone have a nice tree/graph/mesh view to show transactions? I know blockchain.info has something like that, but it's a bit limited in the way you can view the data.

As for those calling me a troll, that's fine. The central point of my comment is what we're talking about here.. everyone seems stuck on my calling them Magic: the Gathering Online Exchange.
