Managing bidders and buyers
While all eBay members can participate in bidding and buying, as a seller you might prefer to limit your sales to people you feel comfortable with, such as those who have positive Feedback scores. We offer several ways to help you define who can bid and buy your items.
Viewing bidder information
During an auction, sellers can see the user IDs of all bidders.
Anonymous IDs are shown to all other members.
Blocking bidders and buyers
If you don't want to sell your items to certain members, you can add their user IDs to a blocked list.
Members on your blocked list can't bid on or buy any of your items until you remove them from the list.
You can block up to 5,000 user IDs.
By default, blocked members are still able to contact you about your listings. You can change this setting in My eBay > Account > Site
Preferences > Buyer
To add a member to your blocked list:
Enter the user IDs of the members you want to block.
To remove a member from your blocked list:
Delete the user ID of the member from the text box.
Setting up buyer requirements
You can specify buyer requirements to manage the types of buyers who can bid on or buy your items. Setting up buyer requirements reduces your exposure to buyers who might make sales difficult for you, although it also reduces the number of potential bidders and buyers for your items. You can specify buyer requirements for all your listings, or you can specify the requirements only for particular listings.
To add buyer requirements to all of your listings:
Go to My eBay > Account > Site preferences.
In the Buyer requirements section, click Show, and then click Edit.
On the Buyer Requirements page, select your buyer requirements. For example, you might not want to do business with buyers who:
Don't have a PayPal account
Have unpaid items recorded on their account
Are registered in countries you don't ship to
Have reportedly violated eBay policies
Have a negative Feedback score
Are currently winning or have bought a large number of your items in the last 10 days
If you want to apply these settings to all current and future listings, select the Apply above settings to current and future listings check box.
If you want to prevent blocked buyers from sending you questions about your listings, select the Do not allow blocked buyers to contact me check box. Remember, you also need to add the buyers to your blocked list.
Click Submit to save your requirements.
To add buyer requirements for a specific listing, specify your requirements in the listing form.
In general, you shouldn't cancel bids on your listings. However, there are a few reasons you may need to cancel a bid:
A bidder contacts you to back out of the bid.
You cannot verify the identity of the bidder after trying all reasonable means of contact.
You end your listing early.
Important: Bids cannot be reinstated after they've been canceled.
To cancel a bid:
Enter the item number, the user ID of the member whose bid you're canceling, and the reason you're canceling the bid.
