I mostly buy on ebay and its been hit and miss with sellers leaving feedback. It ticks me off cause I always paypal within minutes of winning an auction that I sometimes don't get feedback even after leaving it for the seller, which is something I view as their responsibility and part of the deal.

I can see this fixes only some of the probs though and opens up avenues for more scammers. For a small seller, this seems to have no advantages at all.

I don't think this new policy will go long without changes, too ripe for potential abuse. Most of the people I've encountered have been great, but there have been a few of the other kind.
