Not sure, but it seems strange behaviour. I usually bid in a small corner of the Ebay world so I get to recognise the identities of the regular bidders. I have never come across another bidder who has retracted so much stuff. Once in a blue moon you will find a bidder has one, maybe two retractions against hi name, but 45, someone is having a laugh.

If thats the case Id keep well clear of ths seller.
