I think we can safely say now that EBay is busted. These are of course not real bids but phantom bids and it looks like EBay is not able to do anything about it. Either that or the humans on this planet are even more stupid then I already thought.
I think we can now also safely say that you must never set your maximum bid too high because they will try to up the price a lot with phantom bids as close as they can get to your maximum bid.
