This has nothing to do with the seller or their track record (which, outside of TUG, doesn't look bad at all)
Seeing zero bids doesn't mean there were no bids if the seller ends the auction early for some reason (like mislisted item, or selling on a different platform etc). I've had event tickets listed on both Stubhub and ebay and then cancelled one if they sold on the other... it happens all the time. None of these sites forces you to be exclusive...
