It appears we've been very lucky that the 30+ new eBid members who bought from us during the past two months did not buy more than one or two items! I would be appalled if a new customer bought a large number of items from our stores, and then got a black line through their name because they liked the site too much.
We were once the victim of a mischief-maker. Yes it was annoying, and took a while to sort out. But, eBid refunded our FVFs and we relisted the items. That's one incident in two and a half years. We've continued to accept buyers with zero feedback, and rarely have problems. Sellers have the ability to prohibit sales to new members. Those sellers who choose to encourage them are being punished along with the eager new members. I don't think eBid should be doing this.
