Why is everyone so against low fb? Many of my best buyers had 0-5 fb. It discourages even people with more than your required fb to bid. If you get a bidder who doesn't pay, then file a UPI and move on.
I think gummybear didn't against 0 feedback but she worried of NPB since winner never asked her question before place bid ( while she mentioned to contact her first for 0 feedback ) and never responded back.
