When One Cheater Deleted a Thousand Mario Levels: The Mushroom Kingdom Chaos

When One Cheater Deleted a Thousand Mario Levels (Yes, Really)

Short version: chaos on the Mushroom Kingdom server

Imagine waking up to find a chunk of your community’s creations — years of silly, clever, and absolutely bonkers Mario levels — gone. That’s what happened recently in the Super Mario Maker 2 scene: Nintendo removed over a thousand levels from its servers, calling them “advertising,” and plenty of players suspect the deletions weren’t random.

What actually went down?

Players noticed that a lot of the vanishing stages shared a common tag used by a Discord group called Team Shell. Nintendo appears to have interpreted those tags as promotional content and scrubbed the levels. On top of that, several creators had their Switch accounts temporarily suspended after enough reports piled up against them.

Who’s the suspect?

The community pointed the finger at a controversial former top player known as MT94. He was previously caught cheating by using multiple consoles to play against himself — and now an account linked to him allegedly bragged about using several Switches to report levels en masse. If true, one person managed to trigger Nintendo’s automated moderation by flooding it with complaints.

Why this is such a mess

First, the deletions are permanent: Super Mario Maker 2 doesn’t let you re-upload a stage that’s been banned, even if you edit it. That means entire libraries of community-made levels may be gone for good. Second, an automated system that can be overwhelmed by a single determined user is a design flaw — especially for a game that became a long-running hangout for creators.

Can anything be done?

At the moment, it’s unclear if Nintendo will reverse the suspensions or take action against the alleged reporter. The company hasn’t published a public fix for the reporting system, so affected creators are left waiting — and, honestly, pretty annoyed.

The takeaway

This incident is a grim reminder that even retired-ish online games rely on moderation systems that can be gamed. For the Mario community it’s a painful loss: hours of level design, inside jokes, and creative work wiped out because of a heavy-handed automated response — and possibly one person’s grudge. Fingers crossed Nintendo patches things and gives creators some kind of recourse.
