| Challenge: | Social media platforms face escalating challenges in detecting harmful content that promotes muscle dysmorphic behaviors and cognitions (bigorexia). |
| Approach: | They propose a framework for detecting pro-bigorexia content on TikTok using an expert-annotated multimodal benchmark dataset of over 2,200 Tiktok videos labeled by clinical psychiatrists. |
| Outcome: | The proposed framework improves on fine-grained subcategories while commercial models achieve the highest accuracy on primary categories. |

| Challenge: | Large language models (LLMs) have shown promise in representing individuals and communities, but evaluating their fidelity remains a challenge. |
| Approach: | They propose a framework for aligning large language models with online communities via instruction-tuning and comprehensively evaluating alignment across various aspects of language. |
| Outcome: | The proposed framework shows that it can be used to create high-fidelity representations of people and communities. |
