It is a similar wait and process for buyers being cheated by sellers. I have had to file many claims against flaky sellers and the only difference is that I could leave a negative. After 3 negatives a seller is still jerking people around. However, once a buyer gets 3 NPB strikes, they are NARU'd. There is protection for sellers (Paypal, DC, etc). The only protection for buyers is if they use PP.
The inability to retaliate against honest buyers who are displeased with a crappy seller is what that policy was all about. No matter how each member wants to spin it personally, that was the reason and I think it was a good decision. Too many sellers would simply hold off leaving feedback for buyers until they got their positive and this included those sellers who shipped slow, sent items poorly packaged, didn't send items as described, etc. If they got anything less than positive, guess what...the buyer got the same mark OR WORSE sometimes, even if they were model buyers! That is the whole reason I don't leave sellers positive feedback even today unless they leave it for me first. It started before the policy, but since the policy I have strengthened my belief that sellers who can't/won't leave feedback for a buyer when they receive payment do not deserve it at all. The reality is that sellers need feedback to build their reputation. Buyers don't. You can argue that these new policies make for an uneven playing field, but I would feel pretty confident to argue that there are more lousy sellers than buyers, even today.
