Midjourney Banned Prompt — What To Do When Your Image Won't Generate
Midjourney's content moderation system automatically scans every prompt for words or phrases that violate its community guidelines, blocking image generation instantly when a match is found. This error affects users of all plan levels and can trigger even when the intent behind a prompt is entirely benign. Understanding why the block occurs and how to rephrase your request will get you back to generating images quickly.
Why does this error happen?
How to fix it
Remove Violence, Nudity, or Political Trigger Words
Review your prompt word by word and remove any terms associated with graphic violence, explicit nudity, or politically charged language. Even adjectives or modifiers that imply these themes can activate the filter, so aim to strip out the offending language entirely before retrying. Neutral, descriptive alternatives almost always allow the same creative vision to pass through without triggering a block.
Rephrase Using Descriptive Synonyms
Replace flagged words with evocative but filter-safe synonyms that convey the same visual idea without matching banned patterns. For example, instead of words implying destruction, use terms like 'weathered,' 'ancient ruins,' or 'dramatic tension' to communicate mood and aesthetic. This approach preserves your creative intent while sidestepping the keyword-level triggers that cause the rejection.
Enable /stealth Mode if You Are on a Pro Plan
Pro plan subscribers can activate stealth mode using the /stealth command, which prevents your prompts from appearing in the public gallery and adds an additional layer of prompt privacy. While stealth mode does not bypass content moderation rules, it is useful when working with sensitive-but-permissible creative projects where public visibility is a concern. Type /stealth in any Midjourney channel or DM to toggle it on before submitting your next prompt.
Cross-Reference the Official Banned Words List
Midjourney maintains documentation on prohibited content categories in its official community guidelines and Terms of Service, available at docs.midjourney.com. Before crafting complex prompts, scan this list to proactively identify terms that will trigger a block and build your vocabulary of safe alternatives. Bookmarking this page saves significant troubleshooting time for future projects.
Pro tip
Before submitting a new prompt, run a quick mental audit using Midjourney's three core filter categories — violence, explicit content, and politically sensitive material — and replace any word that could plausibly fall into those buckets with a mood-based or purely visual descriptor instead.
