Content Moderation & Mental Health Support

The app uses Google's Perspective API (free tier) to:

• Prevent inappropriate nominations before submission
• Block content flagged for toxicity, hate speech, harassment, and threats
• Provide location-specific mental health resources when inappropriate content is detected

Without a Perspective API key, the app falls back to built-in profanity detection.

Mental Health Resources:

• Befrienders Worldwide — suicide prevention hotlines worldwide
• Samaritans — UK emotional support (116 123)
• Childline — UK child support (0800 1111)
• NHS 111 — UK urgent health advice
• Mind — UK mental health charity

All API calls are made server-side through Next.js API routes to protect API keys.
