This thread has got me thinking - I've not used Ebay a hell of a lot, but I can see why they've introduced this new policy to protect buyers from big sellers with a few thousand positive feedbacks. I've seen lots of retaliatory negative feedback which affects people with low scores the most. Doesn't the new policy include something along the lines of buyers can't leave negative feedback until a week after the transaction, so they've had time to calm down and sort out any problems with the seller? I don't think it's a very good policy from the seller's perspective mind, but I've generally dealt with good people on Ebay. My way of choosing who not to buy from is a bit like the T-F validation idea - don't buy from sellers who type everything in capitals, who can't be bothered to write full sentences, take photos in focus etc. Also not to buy expensive items because of the risk involved. Paypal can only order a refund if there's money in the seller's paypal account (I think?), so holding the money for a while on expensive items seems like the only way to secure this?
