Thanks for your reply but I don't agree with you. There are many reasons why I could want to place an early bid: one is BIN smashing as you've guessed but it isn't the only one. It often happens that you ask the seller if he/she was willing to post to your country, he/she agrees and when you snipe the auction you discover that it has a requirement on the country that prevents you from bidding (it often happens that the seller doesn't even know of the existance of that requirement, many of them don't even know how to remove it). The result is that you've lost an item that you were interested in.
Apart from this I don't see why the auction that I'm the best bidder for might be placed on the top of the list making me lose all the other auctions that end before it. Maybe there has been a misunderstanding because that couldn't be a feature. Let's say that I have three auctions (1, 2, 3) ending in that order and that I'm the best bidder for auction 3 that's also the last one; I'm the best bidder for it and according to the actual sorting policy it would be placed on the top of the list. I would lose auction 1 and 2 without even trying to place a bid for them. Is this what you expect? I don't think. I hope that I've succeeded in explaining better the situation this time. Thank you.
