Yeah, 68 feedbacks seems odd, but in the end, I don't think this is extraordinarily "fishy" at all. I think a lot of sellers do their feedback all at once, and it appears this guy won auctions that ended Feb. 17 and earlier. Maybe this seller had a bunch of albums the guy was interested in and willing to pay for, and it just so happens that on March 28 was when the seller went back and submitted feedback?
Furthermore, if this were some sort of "fishy" transactions, like an attempt to pump up feedback numbers, what's the point? As several people have pointed out, no one really cares what a buyer's feedback is, and that's what this guy is: a buyer.
And in addition to that, if it was a conspiracy to pump up feedback, why do it in a way that apparently makes people think its "fishy"?
And if you guys can take just one more added point, why would someone try to pump up their feedback by some scam of getting 68 feedbacks from the same seller? If your feedback is 10, and you get 68 from the same person, it only goes to 11...
