Seems that most the topics i read on here recently all have to do with unfair feedbackor defamation.   It just seems that this topic has become very HOT at the moment even though this system has been in place for years now.

one reason is that there are a small number of posters who are posting their own threads AND dragging up old threads to go over the same thing on as many threads as they can get their hands on - stirring the pot so to speak.  This is why there are about 4 or 5 threads that are always near the top in recent days.  Give it a week and those threads will go to page two and not be bumped to the top of page one.

Don't take the number of threads as an indication of widespread problems, it's just agrieved sellers venting and ranting.  I'm not saying that those posters don't have some valid points, just the old "squeaky wheel" getting the most oil syndrome. 

I have been the 'victim' of an unfair negative feedback on another login.  It was early in my eBay selling and I didn't know all the options available to me for a non-paying 'buyer'.  I sent a cancellation request that went unanswered by the 'buyer' and then on day 59 (after no contact) he leaves me negative feedback saying that he paid and I cancelled.  Yet I still am not in favour of sellers being able to leave negative feedback.
