Description

A participatory AI platform for social media that detects hate speech in text and images using culturally aware models. When harmful content is found, it invites community members to co-create counter-narratives. Positive engagement is rewarded through a blockchain-based system, empowering users to shape online discourse and foster racial harmony while reducing the spread of hate.

Detailed Idea

Alignment with DF goals (BGI, Platform growth, community)

This AI-powered platform integrates directly into social media via API/plugin, using multimodal transformers to detect hate speech in text, images, and memes. Culturally tailored NLP models (trained on community-annotated datasets) reduce false positives in dialects or Indigenous languages. When hate speech is detected, the system invites users from affected communities to co-create counter-narratives via a collaborative interface. Federated learning preserves data privacy while improving accuracy. A blockchain layer tracks and rewards effective counterspeech with reputation tokens, redeemable for platform governance rights or charitable donations. Community validation ensures responses align with local values, avoiding top-down censorship.

Problem description

Online hate speech, especially racially charged content, is a persistent issue on social media, fueling division and harming marginalized communities. Existing moderation tools often misinterpret cultural nuances, leading to over-censorship of genuine expressions and under-detection of harmful content. This creates mistrust, silences authentic voices, and fails to address the root causes of online hostility, leaving vulnerable groups unprotected and social divides unhealed.

Proposed Solutions

The solution is a platform that integrates with social media to detect hate speech in text and images while respecting cultural nuances. When harmful content is identified, it engages users from affected communities to co-create meaningful counter-narratives that promote understanding and healing. Positive contributions are rewarded through tokens, encouraging constructive dialogue and empowering communities to shape online spaces for greater racial harmony.
