I have 3 ids on ebay, 2 of which are powersellers at the moment, one with over 1800 feedback since 1998 (thefinderskeepers). I think your taking this feedback thing way to serious. First, never leave feedback unless it's given to you first to avoid extortion. Second, everyone understands there are difficult people out there as in the real world, so your going to get negatives. Third, what is your purpose hear? If you want to make money, provide good customer service and keep your nose clean.
I think I've only ever given 2 negatives, because what purpose would it serve ME? I can block the bidder from buying my stuff so I never have to deal with him again, I don't need to agitate him with a negative. But I checked the feedback YOU leave and it seems that you think it's a fun powerplay or something. Who cares about the odd buyer that burns you, it's an inevitable part of life.
Concentrate your energy on enjoying the fun parts of ebay instead of dwelling on the negatives! Alot of people will never bother to leave feedback since they forget, or maybe they're off their PC or ebay for a while, or whatever, life goes on. I leave a comment in my "item shipped notice" and I usually get about 80% of people leaving me feedback, and 99.99% of my problems get solved. It goes like this, and feel free for anyone to copy this to help to contribute to a happier ebay!
"Thank-you for your quick payment! Your Item has been shipped.
I leave feedback upon hearing that your item has arrived safe and sound and that you are happy with it. Most buyers let me know by leaving a positive feedback, which I can then return.
It was a pleasure doing business with you and I
sincerely hope you enjoy your purchase. Here's a handy link to my auctions, hope you'll be back.

Thank you, Happy eBaying!
