Super Mario Maker 2 Massacre: How One Cheater Triggered Nintendo's Deletion Spree

Over 1,000 Super Mario Maker 2 levels are gone. The community points to a culprit: former cheater MT94, allegedly reporting them in retaliation. A story about user-generated content fragility and the dark side of report systems.

The lights are going out on Nintendo Switch servers. Levels built over years by the Super Mario Maker 2 community have vanished in days, deleted as if they never existed. The official reason? "Advertising content." But for creators, this wasn't dry bureaucracy—it was a personal, unfair penalty. And now the whole community is seeking an answer to one terrifying question: could one person truly damage an archive this badly?

The Hashtag Hunt

The puzzle began with a pattern. Nintendo wasn't deleting randomly. They systematically targeted levels tagged with specific hashtags: #TeamShell and #TS. These weren't random words. Team Shell is a powerful, long-running Discord server—the pulsing heart of the SMM2 community. A place where creators shared codes, collaborated, and tested their builds. Tagging a level #TeamShell was a badge of honor, a signal that said: "Built in our circle, for us." For Nintendo, however—by their bizarre logic—it was advertising. And that became the sentence.

"It appears that Nintendo is removing levels that feature hashtags and some variation on the name 'Team Shell.'"— Lewis Parker (Kotaku)

The Ghost of MT94

But who reported these levels to Nintendo? Scouring forums and Discords, the community found a trail. On one server, a user named LMT referenced the mass deletions with chilling confidence. Someone with "5 Switches reporting shxt" [sic]. That was the key clue. Linking LMT's profile to a YouTube account? The pseudonym MT94. A name that sends shivers through the SMM2 community.

MT94 is no ordinary player. They were once the second-highest-rated Super Mario Maker player in the world. But their glory was built on cheating. They used three Nintendo Switch consoles, creating a co-op loop between their own accounts to artificially boost their ranking. When the fraud was exposed, their accounts were banned. Now, from the exile, they seem to have returned with a new mission: vengeance. The target? Everything bearing the Team Shell mark.

The System's Fragility

The most tragic part is the mechanism. Nintendo doesn't do manual review. The entire operation runs on an automated reporting system. And that's where the real problem lies. One person, with five consoles, can trigger a chain reaction that destroys the legacy of hundreds of blameless creators. Levels from seven years ago, allegedly never violating guidelines, suddenly become targets.

"The truly sad thing is that Super Mario Maker users are also reporting that their Nintendo Switch accounts are being suspended as well, as there seems to be a sort of automatic system in place that suspends a Nintendo Switch account if it's been associated with a certain number of reports."— Lewis Parker (Kotaku)

Collateral Damage

And it's not just the levels. The penalty system is ruthless and spreading. A Nintendo Switch account used to submit reports (even if it's the main account of the perpetrator) can get suspended if reports exceed a threshold. This means MT94's internal allies, or random people using the same console for other games, lose access to their entire digital library. This isn't just a war on levels anymore. It's a war on accounts, on purchase histories, on platform access. Nintendo is enacting a total cutoff.

Who Does This System Serve?

This incident raises a fundamental question: who does such a moderation system truly serve? Its original purpose was to fight genuinely harmful content—paid content, scams, illegal marketing. But in the hands of one determined cheater, it became a weapon of mass destruction. It mirrors cases on major social platforms where reports are weaponized in private feuds. Nintendo, the seemingly unyielding guardian of its brand's quality, has shown a submarine-sized hole in its system.

The Community's Anguished Response

The community's reaction is a mix of rage and despair. Creators who built portfolios in SMM2 for years feel betrayed. Not by competition, not by tech shifts, but by an impersonal algorithm and human malice. Many of these levels were architectural masterpieces that already survived one great cull—the closure of the original Super Mario Maker on Wii U. Now they've fallen to something that feels like a caprice or an inscrutable corporate policy no one understands.

What Now for Team Shell?

The Team Shell server stands at the epicenter. While there's no evidence the server itself did anything beyond branding its creations, it has been informally blacklisted. This sets a dangerous precedent: can any community identifier be deemed "advertising"? Do creators have the right to affiliate with groups? Nintendo is silent. And in this case, silence is worse than any answer, as it leaves room for further speculation and fear.

The Erasure of a Legacy

Finally, we must view this from a wider perspective. Super Mario Maker 2 is a one-of-a-kind phenomenon—a game that let users build real, living digital architecture. Its levels are modern versions of homebrew cartridges, spontaneous bursts of creative joy. Their disappearance isn't just a loss for players. It's a loss for gaming history. Nintendo, as their custodian, has a duty to protect this heritage. Instead, it seems to be protecting only its own often-opaque rulebook. At the cost of thousands of soon-to-be-forgotten works.

FAQ

Who is responsible for the level deletions?

The community points to former cheater MT94, who allegedly reported hundreds of #TeamShell-tagged levels in retaliation for his earlier bans. Nintendo confirms deletions but does not comment on the identities of reporters.

Will the deleted levels return?

Very likely not. Nintendo typically does not restore levels deleted for guideline violations, even after changes are made. The action is considered final.

Is the entire Team Shell server at risk?

Yes. Any creator tagging their levels with #TeamShell or #TS is subject to automated deletion by Nintendo's system, causing massive losses within that community.

Why did Nintendo suddenly start deleting old levels?

The company provides no official explanation. Community theory suggests the system previously ignored these flags, but only after mass reports from a single source did the algorithm trigger a cleanup mode.
