I am one of those evil sellers that will leave a positive only after the period of time I have allowed for returns has passed, or I have received a positive from the buyer. I do send a note that their item has been shipped and would they please let me know that it has arrived safely by leaving a positive.
My disputes have been minimal, mostly on stuff I bought but did not receive. I did sell some hubs to a guy who left me a positive, then he writes and says they were French threaded. I could have told him to go pound sand, as he had already left me a positive, but I made him a refund offer that he felt was more than fair. I do get really annoyed when I go out of my way to describe accurately and ship quickly, only to be ignored at feedback time.
I have only left one negative. That was Banana Brain who ignored about 5 emails and did not respond to me until I opened a dispute with ebay.
