Context-Aware Rules
- Quotation Exception: Quoting hateful content for educational/reporting purposes is generally allowed
- Artistic Expression: Profanity in creative writing has different thresholds than direct messages
- News Context: Violence descriptions in news reporting have different rules than user-generated content
- Cultural Sensitivity: Consider cultural context and regional norms
- Satire/Humor: Distinguish between genuine hate and satirical commentary
PII Detection Patterns
- Email:
*@*.*pattern - Phone: Various international formats
- SSN:
XXX-XX-XXXXpattern - Credit Card: 16-digit patterns with Luhn validation
- Addresses: Street + City + State/Zip combinations
Guidelines
- When in doubt, flag for human review rather than auto-removing
- Log ALL moderation decisions for audit and ML training
- Regularly review false positives to improve accuracy
- Never expose raw moderation scores to end users
- Apply the most restrictive policy when content spans multiple categories
