If you are the seller you get the information on your buyer.
If you are an underbidder, you will get an email that tells you when you are outbid.
If you didn't bid, there is no reason for eBay to use up valuable server space to post information they have no reason to believe you are interested in.
Bid. Bid your maximum(don't forget to allow for shipping costs). Bid once. If your bid is too low, you will lose. If you bid more than anyone else, you will win. And not necessarily at your maximum.
It's not rocket surgery.
