The Bidder Who Won Four Auctions and Paid for None of Them
Last updated: August 2026
Over eleven days in October 2023, the same username won four of my auctions and paid for exactly zero. Each time I waited the four days, opened an unpaid item case, waited another four, and relisted. Two of the items had had genuine underbidders who'd moved on by then. I lost about $140 in final sale value and roughly three weeks of listing time to one person who, as far as I can tell, was just bored.
What I didn't know until the fourth round was that I could have stopped it after the first. It takes about forty seconds.
To block a bidder on ebay, add their username to your Blocked Buyer List under Account Settings — it holds up to 5,000 usernames and takes effect immediately. That one list has kept the same repeat non-payer off my listings for two years now.
Where the List Actually Lives
The setting is buried three levels deep and eBay has moved it at least twice, which is why most sellers never find it. From My eBay, go to Account, then Site Preferences, then look for Buyer Requirements and open Blocked Buyer List. You paste usernames into a plain text box, one per line, and save.
That's the whole mechanism. No confirmation email, no waiting period, no notification to the person you've added. They simply stop being able to bid on or buy your items, and if they try, they see a message saying the seller isn't accepting bids from them. They aren't told why and they aren't told who.
The direct URL is worth bookmarking because the menu path changes: ebay.com/bmgt/BuyerBlock. I keep it in a folder with my other seller tools, since hunting through Site Preferences at the moment you're annoyed is its own small punishment.
A few properties of the list that took me a while to learn:
- It holds up to 5,000 usernames, so you will never run out of room
- It applies to every listing you have, current and future, immediately
- Removing someone is just as instant — delete the line, save
- The person is never notified, and there's no public record of it anywhere
In January 2024 I sat down and pasted in 23 usernames I'd collected over about two years in a note on my phone. It took four minutes. Unpaid item cases on my account went from roughly one a month to two in the following twelve months, and both of those were new names rather than repeats. That's the clearest before-and-after I have on any seller setting.
Alongside the block list, and honestly more useful for prevention, is the Buyer Requirements panel on the same screen. Instead of naming individuals, it sets conditions: block buyers with two or more unpaid item strikes in the last twelve months, block buyers with a feedback score below a threshold, block buyers whose registered address is in a country you don't ship to. Those rules work on people you've never met, which is the whole point — a block list only ever catches someone after they've already cost you something.
Here's where I'd temper the enthusiasm. The unpaid-strike filter sounds like it should end the problem outright, and it doesn't, because strikes take time to accumulate and a determined time-waster can open a new account in about four minutes. I've had a non-payer come back under an obviously related username — same city, same bidding pattern, same three-day silence — and there is nothing in the block list that catches that. You block the new name and wait to see whether a third one appears.
My opinion, and I hold it loosely: eBay could solve most of this by making immediate payment required the default on Buy It Now listings rather than an option you have to find. It exists, it works, and it eliminates the unpaid problem entirely for fixed-price items — the buyer simply cannot commit without paying. Why it's off by default I genuinely don't know. There may be a conversion argument on eBay's side that I'm not seeing.
For auctions, immediate payment isn't available, which is exactly why auction sellers end up maintaining the longest block lists. If most of your listings are fixed-price, turn immediate payment on and you'll find the whole category of problem mostly disappears.
Keep a running note of usernames as they happen rather than promising yourself you'll remember. Mine lived in my phone for two years before I got round to pasting it in, and every one of those names had cost me something in the meantime.
Who Belongs on the List, and Who Doesn't
Blocking is cheap, permanent, and invisible, which makes it easy to overuse. The people who genuinely belong on the list are the ones who have cost you money or time in a way that will repeat. Everyone else is a bad day.
The clear cases, in my experience, are the non-payer who has done it more than once, the buyer who opens a not-as-described case on an item you photographed exhaustively and then returns something different, and the serial retracter who bids up an auction and pulls out in the last hour. That last one is the most damaging and the least discussed — a retracted bid in the final hours can scare off genuine bidders who see the price spike and move on.
The cases where I'd wait: someone who asks a lot of questions, someone who leaves neutral feedback, someone who requests a return for a legitimate reason. None of those are the same as a person who costs you a sale.
In April 2024 I blocked a buyer for what I later realised was a courier's fault. He'd opened an item-not-received case on a parcel that had genuinely been delivered to the wrong street, and I was irritated and quick about it. I found the tracking error nine days later, unblocked him, and messaged an apology. He bought two more things that year. I'd been treating the list as a verdict rather than a filter (which is a fairly good description of most bad decisions I've made as a seller).
Does blocking a buyer remove their feedback?
No — and this is the misunderstanding that gets people into trouble. Blocking prevents future bids and purchases; it does nothing to feedback already left, and it cannot be used as a response to negative feedback. If the feedback was genuinely against eBay's policy — profanity, a threat, feedback about something outside the transaction — you report it through the feedback removal process instead, which is a completely separate mechanism with its own criteria. Blocking someone after they've left a negative changes nothing except that they can't buy from you again. I've watched sellers block and then wait for the feedback to disappear, and it simply sits there.

The limitation worth knowing: a block stops bids and purchases, but it does not stop messages. A determined person can still contact you through eBay's messaging system after being blocked, and the only remedy for that is reporting them. I've had exactly one person do this and eBay handled it within a day, but the gap surprised me — I'd assumed a block was total.
My uncertainty here is about scale. I don't know whether a large block list has any effect on how eBay treats your listings. It seems plausible that blocking several hundred buyers narrows your audience in ways the search algorithm might notice, and I've never seen anyone test it or eBay comment on it. My list is 25 names, which is far too small for the question to matter, so I'm speculating.
What I'd recommend is treating the decision to block a bidder on ebay as reversible, because it is. Add the name while you're annoyed if you must, but revisit the list once a year and take off anyone whose story you can no longer remember. Mine has lost three names that way, and one of them turned into a repeat customer.
The list is a tool for preventing repetition, not for settling scores. Used that way it's one of the highest-value four minutes available in your account settings.
The Settings That Stop It Happening in the First Place
A block list is reactive by design — it only ever names people who have already cost you something. The Buyer Requirements panel sitting directly above it is the preventive half, and it's the one I'd set up first if I were starting over.
These are conditions rather than names. Each one is a checkbox with a threshold, and once set they apply automatically to every listing you run, screening people you've never encountered.
The ones I actually use:
- Two or more unpaid item strikes in twelve months — the single highest-value filter, and the one most sellers leave off
- Policy violation reports — four or more in the last month
- Registered in a country I don't ship to — stops the message that begins "will you ship to..."
- No linked payment method — screens accounts that can't complete a purchase
There's also a filter for buyers with a feedback score of 1 or lower, or below zero, and I have mixed feelings about it. Every legitimate buyer starts at zero, and a new account is not evidence of anything. I ran it for about six months, and while my unpaid cases didn't change measurably, I did get two messages from people asking why they couldn't bid. I've had it switched off since.
In June 2024 I turned on the unpaid-strike filter after the fourth non-payment of that year. Over the following twelve months I had two unpaid items against 380-odd sales, down from what had been running at roughly one a month. I can't prove the filter caused all of that — my mix shifted toward fixed-price listings in the same period, which matters — but it's the only setting I changed deliberately.
Can I stop unpaid items entirely?
On fixed-price listings, yes — turn on immediate payment required and the problem disappears completely. The buyer cannot commit to the purchase without paying for it in the same action, so there's no window in which an unpaid item can exist. It's in the listing form under payment options, and it's off by default on most listing flows. On auctions it isn't available, because the bidding model requires a gap between winning and paying, which is exactly why auction sellers carry the longest block lists and why unpaid items are effectively an auction-only problem.
If your listings are mostly Buy It Now and you're still fielding non-payers, this one checkbox ends it today.
Worth knowing that Seller Hub shows you the pattern before you'd otherwise notice it. Under Orders there's an Unpaid Items view, and the same username appearing twice in it is the signal to act. I'd been treating each non-payment as an isolated annoyance for two years before I looked at that view and saw one name three times.
The other setting that quietly helps: your handling time. Sellers who ship in one business day get better placement, and better placement brings a different mix of buyers — the ones searching with intent to buy now rather than the ones idly bidding across forty auctions. That's an indirect effect and I can't quantify it, but the correlation in my own account is hard to miss.
Between requirements, immediate payment, and the option to block a bidder on ebay individually when someone still slips through, the three together cover nearly everything. Set the first two once, and the third becomes a rare four-minute chore rather than a monthly one.
None of this is visible to buyers, and none of it costs anything. It's about fifteen minutes of settings that most sellers never open.
What to Do About the One Who Already Got Through
Blocking is what you do after the transaction is resolved. Before that, there's a sequence that decides whether you get your fees back and whether the item goes back on sale quickly, and doing it in the wrong order costs you both.
For a non-payer, the process is mostly waiting. eBay opens an unpaid item case automatically four calendar days after the sale if the buyer hasn't paid. Once it closes, your final value fee is credited back and the item can be relisted. You don't need to chase anything — the automation handles it — but you do need to not cancel the order yourself, because a seller-initiated cancellation is recorded against your account while an unpaid item case is recorded against theirs. , according to Federal Reserve economic indicators
That distinction cost me real money before I understood it. In February 2023 I cancelled three unpaid orders manually because I wanted the items relisted before a weekend. All three went down as seller cancellations, my cancellation rate crossed eBay's threshold, and I lost Top Rated Seller status for the following quarter — worth roughly a 10% discount on final value fees that I then didn't get for three months. The buyers, meanwhile, took no strike at all.
So the order of operations that actually works:
- Wait the four days and let eBay open the case; do not cancel
- Let the case close on its own — another four days — and take the fee credit
- Relist through the Unsold view in Seller Hub, which keeps your original photos and description
- Then, and only then, add the username to your blocked list
Relisting from the Unsold view matters more than it sounds. Building a fresh listing loses the item's history and starts its search placement from nothing, while a relist carries some of it forward (and takes about eight seconds rather than twenty minutes).
Will eBay refund my fees if the buyer never pays?
Yes, automatically, once the unpaid item case closes — but only the final value fee, not the listing fee if you paid one. The credit appears on your next invoice rather than as a separate refund, which is why sellers often think it hasn't happened. Check your fees breakdown in Seller Hub rather than looking for money arriving. The thing that voids this is cancelling the order yourself: a seller cancellation returns the fee too, but it books the cancellation against your metrics, so you've traded a fee credit for a defect. Wait the eight days. It's slower and it's strictly better.
For a buyer who paid and then caused a different kind of problem — a false not-as-described claim, a returned item that wasn't the one you sent — the path is different and less satisfying. Report the buyer through the order's report link, provide photographs, and accept that eBay usually funds the refund on the buyer's side regardless. What the report does is build a record; buyers with enough reports do eventually get filtered by the policy-violation requirement. It's slow and it doesn't help you this time.
Once any of that is finished, the decision to block a bidder on ebay takes forty seconds and closes the loop permanently. Keep the note of usernames somewhere you'll actually see it — mine is a note in my phone titled with the word "never" — and paste them in whenever you happen to be in settings.
The pattern across all of it: the platform's automation is slower than your patience but better for your account than anything you do manually. Let it run.
How the Other Marketplaces Handle the Same Problem
eBay is the only major marketplace where non-payment is possible at all, and understanding why explains a lot about where you should be listing what.
The gap exists because auctions require a delay between winning and paying. Every fixed-price marketplace collects the money at checkout, so the transaction either completes or doesn't — there's no state where someone has committed to buy and hasn't paid. Poshmark, Depop, Mercari and Vinted all work this way. You cannot have a non-payer on Poshmark because payment is the purchase.
What those platforms have instead is a blocking mechanism aimed at harassment and lowball offers rather than payment:
- Poshmark — block from the user's profile; they can't comment, offer, or buy, and their existing comments on your listings disappear
- Depop — block from the profile, which also removes them from your followers and hides your listings from them
- Mercari — block via the user's profile page; mostly used against repeat lowballers and message spam
- Vinted — block from the profile, which stops messages and offers
Two things differ from eBay in a way that catches people out. First, blocking on those platforms is usually visible in effect — the person notices your listings vanished — where an eBay block is silent. Second, none of them have anything equivalent to Buyer Requirements. There's no rule-based screening, no filter for people with a history of problems. You block individuals, one at a time, after the fact.
The practical consequence is that the problem you're managing changes by platform. On eBay it's non-payment and it's mostly on auctions. On Poshmark and Depop it's lowball offers and comment spam, which cost you time rather than sales. On Mercari it's people who buy and then immediately request a cancellation, which is closer to eBay's problem but resolves faster because the money was already taken.
Where this becomes genuinely awkward is when you list the same inventory across several platforms, because your block lists don't travel. A person you've blocked on eBay can buy the identical item from you on Mercari without either of you knowing. There's no shared reputation layer across marketplaces and there almost certainly never will be, given they're competitors.
What does travel across platforms is the listing work, and that's the part worth arranging properly. The same item needs its own description, category, and shipping setup on each marketplace, and when it sells in one place it has to come down from the others quickly — on eBay a cancellation for an item you no longer have is a defect against your account, which is the same metric that unpaid items and manual cancellations feed into. Crosslisting tools handle both halves: write once, publish everywhere in each platform's format, and pull the rest down automatically on a sale.
My own arrangement is boring and it works: auctions stay on eBay because that's where auction buyers are, fixed-price items go everywhere, and immediate payment is on for all of the fixed-price listings. That combination means the ability to block a bidder on ebay is something I use perhaps twice a year now rather than monthly.
If you're mostly on the social marketplaces and wondering whether you're missing a settings panel like eBay's, you aren't. It doesn't exist there. Block individuals as they appear, and don't expect the platform to screen anyone for you.
Four Minutes, Once
Pasting 23 usernames into that box took me four minutes and my unpaid item cases went from about one a month to two in the following year. I'd rate the Buyer Requirements filters above the list itself, though — screening people you haven't met yet beats naming people who've already cost you something. The honest caveat is that none of it stops a determined person from opening a fresh account, and I've watched exactly that happen.
When my listings started going out across several marketplaces, I moved the write-once-publish-everywhere part to Closo, mostly so a sale in one place pulls the item from the others before someone buys it twice.
