How Do I Block A Bidder On Ebay?

Yes, you can block a bidder on eBay as of 2026; it prevents them from placing bids or buying your items but lets them still view your listings.

What happens when you block a bidder?

Blocking a bidder hides them from your sales but doesn't remove them from your listings—your items remain visible in search and storefronts.

Here's the thing: after you block someone, they can still scroll through your active listings and add items to their cart. The block only kicks in at checkout, where they'll see a message saying you're not accepting purchases from them. (No dramatic "blocked" warning appears anywhere else on eBay.) You can also flip a switch to stop blocked users from messaging you entirely.

How do you actually block a bidder?

You block a bidder through Seller Hub under Site Preferences → Buyer Requirements → Blocked Buyers.

Sign in to your eBay Seller account.
Click Account → Site Preferences.
Under Seller Account, select Buyer Requirements.
Click Edit next to Blocked Buyers.
Type in the username and hit Add, then Submit.
Optionally toggle “Don’t allow blocked buyers to contact me” and Submit again to save.

eBay lets you block up to 5,000 buyers per account. The system only shows a generic decline notice when the blocked user tries to purchase—no fanfare, no drama.

What if blocking didn't stop the bidder?

If blocking fails to stop a problematic bidder, escalate to reporting them or tightening automated buyer rules.

Report the buyer: In Orders, open the transaction, choose More actions → Report buyer, and pick reasons like “shill bidding” or “abusive behavior.”
Tighten buyer requirements: Bump the minimum feedback score to 98 and block buyers with unpaid items via Buyer Requirements.
Enable Seller Protection: Turn on Seller Protection Program in Seller Dashboard to flag risky bidders without a full block.

How can you prevent problem bidders before they even bid?

Set automatic buyer rules to block buyers with unpaid items and low feedback scores before they bid.

Here's what works best: enable “Block buyers who have unpaid items” and set a minimum feedback score (say, 95) in Buyer Requirements. Turn on Delivery Address Verification to catch mismatched shipping details. Review your Blocked Buyers list monthly and adjust thresholds based on what you're seeing. Address unpaid item cases quickly to keep your seller metrics strong and scare off repeat offenders.
