I've been waiting for a response from eBay but up to this point have heard nothing. If the policy states that 4.8 DSRs get you advantaged in "Best Match" then it should not matter the number of 1s or 2s. The vast majority of customers were happy. What concerns me is that eBay keeps moving the goal posts for sellers. If this is the new policy then their needs to be more transparency about who is giving 1s and 2s and we all know that ain't happening.
This Cartoon says it all. In case you couldn't tell who's who: eBay is Lucy and Sellers are Charlie.
