yes hopefully they will change this
I agree with Ftpyd, I think it should be at least like eBay, only buyer can put negative. Because this way the sellers will try to be good and respect the marketplace, not scamming here. if they do it quickly becomes obvious. Retaliatory feedback is no good, also if you avoid leaving negative because don't want a retaliation it doesn't work all the time. It is 98% of time the buyer that gets screwed so they should have the right for negative or no feedback, plus a short feedback description is good idea too.
