it is quite feasible for an excellent buyer, who has diligently purchased MANY items over a number of years - to still have zero feedback. If that buyer then tries to buy an item which a seller has defined as 'no zero feedback bids accepted' - BOTH the seller and the buyer LOSE OUT on what could have been a straight forward transaction on the parts of both members.

Unless needing more than 10 feedback to reply on these boards is important why would it matter if a buyer had zero feedback after many years and hundreds of purchases? No seller has the ability to block buyers with zero feedback.
