Most “Banned Word” lists are set to “whole word” by default to prevent mistakes.(This is most likely and I never really tested or know anything haha)

band word types: muse

The system actually runs: /\bmuse\b/ (It automatically adds word boundaries).

Result: This ban FAILS to block https://motionmuse.ai/ because it only looks for the whole word “muse” surrounded by spaces or punctuation.

In this case, you should ban /motionmuse/i instead of just muse

🧠 Full Regex Guide for Prompt Filtering and Banning (I don’t know if this is true or not anyway…)

• /i → case-insensitive flag. Matches letters regardless of case. Example: /ahegao/i → matches ‘Ahegao’, ‘AHEGAO’, etc.

• \b → word boundary. Ensures the match is a whole word, not part of a longer word. Example: /\bvore\b/ → matches “vore”, but NOT “carnivore”

✅ Combine /i + \b for safe, accurate filters: /\b(vore|gore|nudity)\b/i → blocks keywords regardless of case, avoids substring errors.

• .* → greedy match: matches as much as possible. Example: /cute.*girl/ on “cute baby girl and cute big girl” → matches from first “cute” to last “girl”

• .*? → non-greedy match: matches as little as possible. Example: /cute.*?girl/ → matches “cute baby girl” only

⚠️ In short prompts with only one girl, .* and .*? behave the same. Difference matters only when multiple targets exist in the same string.

• s? → optional “s”, allows singular or plural forms. Example: /\bcubs?\b/ → matches “cub” and “cubs” /thongs?/ → matches both “thong” and “thongs”

🧩 Common Patterns: /\b(term1|term2|term3)\b/i → safe multi-keyword match ; Matches: term1 OR term2 OR term3 /keyword1.*?keyword2/i → non-greedy span between phrases ; Matches: keyword1… AND… keyword2 /\bsomeword\b.*ContentLabel/i → flag word only when paired with OUR CUSTOM 18+ label /cute.*(boy|girl).*ContentLabel/i → complex combo with fallback grouping ; Matches: “cute innocent girl... ContentLabel”
