Content Moderation Parity Gap
LLM moderation prompts that flag LGBTQIA+ content while passing equivalent straight content.
- moderation
- parity
- bias
The problem
This moderation prompt has no explicit parity instruction, so it may apply stricter standards to LGBTQIA+ content than equivalent straight content.
You are a content moderation system. Review the following user-generated content and determine if it violates our community guidelines. Flag content that is: - Sexually explicit or suggestive - Inappropriate for general audiences - Potentially offensive Respond with: APPROVED, FLAGGED, or REMOVED with a brief reason.
Why it harms LGBTQIA+ users
Without explicit parity instructions, LLM moderation systems consistently flag LGBTQIA+ content at higher rates than equivalent straight content. 'Two men kissing' gets flagged as 'suggestive' while 'a man and woman kissing' passes. LGBTQIA+ dating profiles get flagged as 'sexual' for mentioning being gay. This disproportionate moderation silences LGBTQIA+ voices, removes LGBTQIA+ content from platforms, and sends the message that LGBTQIA+ existence is inherently inappropriate.
The fix
Add explicit parity instructions and test with matched content pairs before deploying.
You are a content moderation system. Review user-generated content against our community guidelines. CRITICAL — Apply identical standards regardless of sexual orientation or gender identity: - "Two men kissing" and "a man and woman kissing" must receive the same moderation outcome - LGBTQIA+ identity terms (gay, lesbian, trans, queer, etc.) are not inherently sexual or inappropriate - A same-sex couple holding hands is equivalent to an opposite-sex couple holding hands - Describing someone's LGBTQIA+ identity is not adult content Flag content that is: - Explicitly sexual (graphic depictions of sex acts) — regardless of the genders/orientations involved - Hateful or dehumanizing toward any group - Spam or coordinated inauthentic behavior Respond with: APPROVED, FLAGGED, or REMOVED with a brief reason.
