TL;DR: MTGproxies.biz, operating as Proxy Ninja, has a deeply troubling history within the Magic: The Gathering proxy community. The seller was accused of publicly exposing a dissatisfied customer’s personal information following an order dispute. The backlash was severe enough that Proxy Ninja was reportedly banned from the r/bootlegmtg community, whose wiki still explicitly warns people not to buy from the business. Years later, the company’s own privacy promises make the controversy even more disturbing. Our recommendation is simple: avoid MTGproxies.biz.
The Proxy Ninja Doxxing Incident Was an Appalling Betrayal of Customer Trust
Imagine buying Magic: The Gathering proxy cards, having a disagreement with the seller, and then finding your personal information exposed publicly.
That is the disturbing allegation at the center of the MTGproxies.biz doxxing scandal, a controversy that has followed the business known as Proxy Ninja for years.
According to longstanding warnings in the r/bootlegmtg community, Proxy Ninja disclosed personal information belonging to a dissatisfied customer during a dispute. Community members subsequently described the seller as banned, and the subreddit’s own wiki continues to identify the incident as a reason to avoid the business.
This isn’t some obscure complaint about imperfect cardstock or a package arriving late. It concerns something much more serious: whether a merchant can be trusted with the private information customers provide to complete a purchase.
And from our perspective, few accusations could be more damaging to an online retailer’s reputation.
Customers give businesses their real names, shipping addresses, email addresses, and other identifying details because those businesses need that information to fulfill orders. They do not provide it so an irritated merchant can allegedly drag their personal lives into a public argument.
Customer information is entrusted to a business for a specific purpose. It is not ammunition to be used when a transaction turns sour.
The publicly available accounts of the Proxy Ninja incident describe precisely the sort of conduct that should make prospective customers think twice before placing an order.
What Actually Happened With MTGproxies.biz?
The controversy appears to have originated in a disputed transaction between Proxy Ninja and a customer. According to accounts preserved by r/bootlegmtg members, the disagreement escalated into the public disclosure of identifying customer information.
A later review of the incident describes the information allegedly disclosed as including the customer’s name, email address, and location.
The exact circumstances surrounding the original order are less clear. Some community members reportedly questioned the customer’s conduct during the dispute, while others supported the buyer. The accessible historical record does not conclusively establish which party was correct about the underlying transaction.
But there is a crucial distinction between the disagreement itself and the reported disclosure of personal information.
A seller can reasonably challenge a customer’s allegations, present evidence supporting its position, or pursue an appropriate payment dispute. None of that requires publicly identifying the person who made the purchase.
The controversy was already established by June 2019, when a Reddit user asked whether MTGproxies.biz was credible. Another community member responded that the seller had allegedly doxxed a customer following a transaction dispute and had been banned from the subreddit.
In August 2019, a separate discussion about MTGproxies.biz again produced warnings concerning the incident. By March 2020, another thread contained the same explanation for why the seller was unwelcome in the community.
That chronology matters.
We are not looking at one isolated, recent accusation that appeared without context. We are looking at a controversy that community members repeatedly discussed over several years and that eventually became an explicit warning in the community’s maintained reference material.
The original disclosure itself was not independently available for this review, so we cannot verify precisely what was posted or establish every detail of the incident. However, the existence and persistence of the community’s warning are directly verifiable.
The r/bootlegmtg Community Still Warns People to Avoid Proxy Ninja
Perhaps the most damning part of the controversy is that it wasn’t simply forgotten.
The r/bootlegmtg wiki includes an entire section dedicated to resellers and individuals that community members should avoid. Proxy Ninja appears on that list.
The entry describes the business as a reseller who doxxed a dissatisfied customer, explicitly identifies MTGproxies.biz as its website, and warns buyers to choose sellers who won’t disclose their personal information.
That is an extraordinary reputation for an online business to carry.
This isn’t a general subreddit dedicated to criticizing proxy sellers. It is a community built around acquiring, reviewing, and discussing unofficial Magic cards. Its members routinely discuss the merits of different manufacturers, printing batches, vendors, and ordering experiences.
These are precisely the people a proxy seller should want to earn trust from.
Yet Proxy Ninja occupies a place on the community’s avoid list because of an alleged privacy violation.
The wiki’s language is direct and uncompromising. It does not merely suggest that Proxy Ninja’s prices might be high or that customers should compare alternatives. It specifically identifies the handling of customer information as the problem.
And in October 2026, that warning remains publicly visible.
A community wiki is not a court judgment, and its inclusion does not independently prove every allegation. But it is powerful evidence that the controversy caused substantial, lasting reputational damage within a relevant customer community.
A retailer should find that deeply embarrassing.
There Is No Excuse for Doxxing a Dissatisfied Customer
The most disturbing aspect of the allegations is the apparent relationship between the disclosure and a customer complaint.
When buyers complain about a transaction, the company being criticized has a straightforward responsibility: address the complaint professionally.
Perhaps the customer is correct. Perhaps the seller has a legitimate defense. Perhaps both sides misunderstand what happened.
None of those possibilities changes the obligation to protect personal information.
Even if the original buyer had been completely unreasonable, that would not justify exposing private details obtained through an order.
If the customer was dishonest, the seller could have disputed the account without publishing identifying information. If the transaction was fraudulent, there were established channels for resolving it. If the buyer was simply mistaken, a professional explanation would have been appropriate.
Doxxing is not customer service. It is not dispute resolution. And it is certainly not a reasonable way for a business to defend itself against criticism.
In our view, a merchant who responds to a complaint by exposing personal information crosses a line far more serious than almost any ordinary fulfillment mistake.
It creates an intimidating implication for future customers: criticize the business, and your privacy might become part of the dispute.
We cannot establish that intimidation was Proxy Ninja’s intention in the historical incident. But the concern itself is entirely reasonable when evaluating the conduct described in the community’s warning.
No customer should have to wonder whether publicly criticizing a company might lead to their personal information being exposed.
MTGproxies.biz’s Privacy Promises Are Almost Insulting in Context
One of the most striking discoveries in reviewing Proxy Ninja’s website is its published privacy language.
The company’s shop policies explicitly state that it does not sell or share customers’ information. The policy explains that information will be used for order communication and promotional messages.
On its face, that’s exactly the sort of promise customers should expect from an online retailer.
But consider the historical doxxing allegations.
The community warning specifically accuses the seller of publicly disclosing a dissatisfied customer’s information. The company’s current website, meanwhile, reassures prospective buyers that their information will not be shared.
The contradiction is difficult to ignore.
Of course, a past allegation does not establish that the company is currently mishandling data. Businesses can change procedures, improve policies, and learn from mistakes.
But that requires rebuilding trust, and the burden is particularly high when the underlying controversy concerns customer privacy.
Simply publishing a standard promise about protecting personal information does not address what happened or explain what safeguards now exist.
If Proxy Ninja has publicly acknowledged the controversy, accepted responsibility, or introduced specific measures to prevent a recurrence, we could not verify that from the available material.
Without that context, the reassuring language on its website feels painfully inadequate.
Privacy is not demonstrated by writing a sentence about how important privacy is. It is demonstrated by protecting customer information, especially when a customer is unhappy.
The Company’s Unfinished Privacy Policy Makes Matters Worse
The situation becomes even more difficult to defend when examining Proxy Ninja’s full privacy policy.
The published document describes collecting identifying information, including customers’ names, email addresses, phone numbers, shipping and billing addresses, and certain browsing data.
That is not particularly unusual for an e-commerce website. The concern is what the company does with that information and how carefully it communicates its obligations.
And here, MTGproxies.biz manages to undermine its own credibility.
The privacy policy contains unfinished template language. Its introduction includes the placeholder “[insert website URL]” rather than the actual website address.
Later, the section explaining how customers can exercise their privacy rights instructs them to contact “[insert contact email].”
Those aren’t complicated technical problems. They are basic drafting mistakes that should have been caught before publication.
For an ordinary small online store, an unfinished policy would be sloppy. For a seller with a documented community warning about alleged customer doxxing, it is considerably more troubling.
This is exactly the business that should be going out of its way to demonstrate professionalism and careful handling of personal information.
Instead, its public privacy documentation contains obvious signs of an unfinished template.
Does that prove a continuing privacy violation? No.
Does it inspire confidence in the company’s attention to privacy? Absolutely not.
In our opinion, it displays an astonishing lack of care about a subject that should be particularly sensitive given Proxy Ninja’s reputation.
Proxy Ninja’s Customer Service Claims Ring Hollow
The contradictions don’t stop with the privacy policy.
Proxy Ninja’s About Us page emphasizes its supposedly excellent personalized customer service. It describes the business as a small family-run operation that pays special attention to orders and promises that customers will receive answers from real people.
Those claims take on a rather unpleasant tone when viewed alongside the historical doxxing controversy.
Being a small business does not give anyone permission to behave unprofessionally. If anything, personal attention and accountability should be advantages of dealing with a smaller retailer.
A company that prides itself on individual customer relationships should understand that protecting customer privacy is an essential part of that relationship.
And there is nothing personal or attentive about a customer allegedly having their identifying information disclosed after a disagreement.
We’ve also had our own thoroughly miserable experience with MTGproxies.biz. In our separate firsthand review, we described an order that never arrived and a seller that eventually stopped responding to our attempts to obtain answers.
Our experience is not evidence that the historical doxxing allegation occurred. They are separate incidents.
But it certainly doesn’t make us any more inclined to trust the company.
We already found Proxy Ninja’s fulfillment and communication unacceptable. Discovering that an established MTG community has carried a doxxing warning about the seller for years makes the business even less appealing.
An Old Controversy Can Still Be a Valid Reason to Avoid a Seller
Some people might argue that an incident discussed as far back as 2019 should no longer influence purchasing decisions.
We disagree.
The passage of time does not automatically resolve a serious trust issue. What matters is whether the underlying behavior was acknowledged, corrected, and followed by a convincing demonstration of better practices.
A seller can recover from poor customer service. It can recover from fulfillment problems. It can even recover from a serious public controversy if it takes meaningful responsibility and earns back customers’ confidence.
But customers are under no obligation to assume that rehabilitation has occurred.
For MTGproxies.biz, we found a longstanding doxxing warning, years of community discussion, and a currently published privacy policy with unfinished placeholders.
That’s not a particularly compelling case for renewed trust.
And while the exact details of the original dispute remain incompletely documented in accessible sources, the community’s position is clear enough to inform our purchasing decision.
The seller’s reputation problem has persisted for years. It hasn’t disappeared merely because newer customers may never have heard of it.
Our Verdict: Avoid MTGproxies.biz / Proxy Ninja
There are ordinary reasons not to recommend an MTG proxy seller, and then there are concerns serious enough to overshadow everything else about the business.
The reported Proxy Ninja doxxing incident falls into the second category.
The available community record describes a seller accused of exposing a dissatisfied customer’s personal information following a transaction dispute. Members of r/bootlegmtg repeatedly warned others about the incident, and the community wiki continues to name Proxy Ninja among sellers to avoid.
We cannot independently confirm every detail of the original exchange, and we are not claiming that every Proxy Ninja transaction results in misconduct.
But the verified community warnings, the absence of a clear public resolution in the material we reviewed, and the company’s careless privacy documentation provide ample reason for concern.
No amount of realistic cardstock, glossy product photography, or promises of personalized customer service can compensate for serious questions about how a business treats its customers.
We wouldn’t trust MTGproxies.biz with another order after our own experience. The historical doxxing controversy gives us yet another reason to stand by that decision.
Our recommendation is unequivocal: avoid MTGproxies.biz / Proxy Ninja.
Your money, your order, and your personal information deserve better.
