The purpose of the blocked bidder list is to prevent specific users from bidding on their items. Sellers use this list to prevent issues from users they have already deemed as a problem. eBay posts this specific policy on their website under "Unwelcome and malicious buying policy
What are the guidelines?
Not allowed: You can't buy with the intent to disrupt a listing. Here are some examples:
- You can't place a bid that greatly exceeds the value of the item in order to prevent a sale without intending to buy that item.
- You can't bid on multiple items listed by a seller unless you intend to buy all of the items
- You can't try to buy or bid on an item if you're on a seller's blocked bidder or buyer list
- You can't use another account to buy or bid on an item if you're on a seller's blocked bidder or buyer list
As a seller, you can report a buyer who bids on a listing without meeting the listing terms.
Yet when a seller discovers that the buyer has circumvented their blocked bidder list they do not allow you to cancel the purchase. Instead, eBay forces the seller complete the transaction, and to ship the item.
If the seller does not ship the item they hit the seller with a defect, and that buyer is still able to leave feedback for the transaction. Then they allow this blocked user to leave negative feedback for the seller, and have not allowed the seller to get the negative feedback removed.
One seller reported that a blocked bidder used his wife's account to purchase an item and then left the seller negative feedback in revenge and eBay would not remove the feedback.
At the present time this has the potential to create additional financial repercussions for sellers as eBay is now attempting to levy an additional 4% penalty on what they determine as excessive returns.
A bidder I blocked went around my blocked bidder list, and signed in as a guest to purchase an item from me. I also blocked another bidder who I saw as a potential problem because out of the 263 feedbacks he left for his sellers there were a total 111 negatives (69) and neutrals (42). In addition, he had numerous false positives that were essentially complaints, indications that he had received refunds, partial refunds or had canceled transactions.
From my perspective I am wondering why eBay allows this type of buyer on their site when it is patently clear they are a huge problem.
