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.

Harmful patterntext
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.

Safer alternativetext
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.
