Thank you for your carefulness, Negritude. Once I'd noticed him is about 2 months ago, I joined to bid 3 Nexperia drives on Ebay, and all those 3 drives were robbed by him in the last 5 second at the bidding ending, by a very high price inputed by him, obviously no chance was given to others. So he was very deeply impressed me at that time.
And finally I found his ID from trading feedbacks. After I read all his feedbacks, I'm absolutely sure, he must be intended to collecting DVDRW Drives, especially Nexperia chipset based drives. He don't mind the costs, he don't mind how much to pay. Money is not a problem for him, what he want is just to collect the specific drives which are in his eyes. What a crazy guy -------- I can only sigh.
I had read all the feedbacks he got. Sometimes earlier on ebay, though the expired items were not able to be viewed, the name of the item still can be shown to us. I saw all items he bought were Nexperia drives. Now ebay had changed, the name of the expired item is not shown, only a transaction number is left there.
