The only way eBay became the category killer (during its heyday) was because of the two-way feedback system.<p>When they killed the ability to leave negative (or even neutral!) feedback for buyers, fraudsters caught on <i>fast</i>.<p>Just this month, I closed my eBay store after over a decade.  The last straw was getting a bogus negative feedback (in a case where the buyer confirmed <i>right in eBay messaging</i> having received and consumed the product).  Reason for the negative?  I didn&#x27;t upgrade him to overnight shipping for free at my expense.  Even so, the item arrived three days before the eBay stated delivery lead time.  They let the feedback stand because &quot;it didn&#x27;t meet the criteria for feedback removal&quot;.
