AuctionBytes is publishing an article in the February 25th issue of AuctionBytes Newsflash about tools sellers can use to research eBay buyer feedback. Sellers who are concerned about eBay's new feedback policy that takes away the ability for sellers to leave negative or neutral feedback ratings for buyers are looking for ways to avoid problematic buyers and bidders. (eBay said it would roll out the feedback change in May.) If you've used any buyer feedback tools, please share your experience.
Update 2/25/08: Here's a link to the article.
