So, is it worth it to leave bad feedback for someone when you know that they'll just probably do the same to you?
I have 125 positive feedback, 0 neutral and 0 negative. I've recently had two semi-bad eBay transactions. One is a buyer who appears to be a deadbeat bidder (0 feedback, supposed to mail a money order which has never arrived) and the other is a seller who hasn't shipped my stuff (it's been over two weeks now -- I just e-mailed him and he said "it went out today!").
In all honesty these guys don't deserve negative feedback, but maybe a neutral. But what's stopping me from doing it is the fact that I know they'll leave "revenge" feedback, even though I did everything right in both cases!
What are your feedback policies when people become a pain in the ebay ass?
