I've recently had the same auction spoiled twice by the same idiot using the Buy Now feature. He did offer to pay by 'chequq' (sic) and the rest of his emails displayed a similar lack of understanding of grammar and spelling. I gave him his first neg as he seemed more interested in selling something to me rather than the other way round.
Now he has a rating of -17 and his username is overstruck: Does this mean that he's been barred, or what?
