Big announcement on NSFW content in System Messages on MakerWorld.
In short it looks like Bambu is formalizing that they don’t really want it on MakerWorld.
Here’s the message I received:
Cleaning Up Sexually Inappropriate Content on MakerWorld
2026-07-04 00:35
Hey everyone,
MakerWorld is for everyone — creators, families, and yes, kids too. That means what shows up in browse, search, and recommendations should feel welcoming and safe for all of them. Lately, some of you have flagged that inappropriate content (NSFW and similar) is still slipping through.
Let’s be clear: MakerWorld doesn’t want or need this content to drive traffic. The issue isn’t that we’re turning a blind eye, it’s that too many of these items are slipping past our current detection systems. We hear you, and we’re already acting on it.
Two problems we’re targeting
We’re seeing this show up in two forms, and we’re addressing both:
-
The model itself is inappropriate — sexually suggestive, explicit, or otherwise low-quality content that doesn’t belong in open spaces.
-
The model is fine, but the cover is used as clickbait — a normal model (say, a bracelet) paired with an unrelated, sexually suggestive cover image to farm clicks.
After your recent feedback, we accelerated review and took action on 1,000+ models, and started cracking down on repeat-offender accounts that push this content through bulk uploads.
Here’s how we’re tackling it right now: our moderators are manually cleaning this up while our tech team builds a stronger detection system. Improving the AI isn’t an overnight fix since it takes a lot of manual labeling and fine-tuning to get right. So for the time being, we’ll be leaning on hands-on human oversight.
How enforcement works
Depending on the severity of the violation, we may:
• Remove the content entirely,
• Pull it from all recommendation surfaces,
• Mark it as NSFW so it’s only visible to users who’ve opted in, or
• Limit its reach (reduced distribution).
For accounts, penalties scale with how often and how seriously they violate the rules, ranging from a warning all the way to a permanent ban.
What we’re doing going forward
• Fast action on reported models, with escalating penalties for repeat offenders.
• Proactive review of existing trending content — not just waiting on reports — with enforcement whenever we find violations.
• Better detection, since the core problem is content slipping past our systems in the first place.
• Dedicated resources so this is continuous work, not a one-time sweep.
• More control for you: NSFW display is off by default. You can double-check your settings at the bottom of your Preferences page.
A note on scope: This isn’t about broadening censorship. We’re focused on content that’s clearly inappropriate for open spaces everyone can see. Borderline cases go through human review, and if we get one wrong, our appeal channels are open and we’ll take another look fast.
How you can help
• See something off? Report it, and we’ll act ASAP.
• Think your work was flagged by mistake? Appeal through our existing channels and we’re prioritizing appeals tied to this effort.
Why it can feel worse than the numbers suggest
This content is only roughly 0.2% of overall traffic over time. So why does it feel so much more prominent? Because this kind of content tends to get high click-through rates. So when a piece slips past our filters, our algorithm sees those clicks and accidentally pushes it to the front page, making it far more visible than its actual volume would suggest.
What’s next
Beyond the work above, we’re also planning a Minor Protection Mode — a dedicated experience designed to keep browsing safe for younger users. This is still just a preliminary idea, we’ll share more as it takes shape.
Thanks for holding this community to a higher standard. We’ll keep you posted.
