    Online illegal content increasingly leverages sophisticated obfuscation techniques to evade detection,creating a growing need for advanced multimodal Open-Source Intelligence (OSINT) analysis. However, even LLM-based single-agent systems often struggle to preserve explicit context across diverse signals and fail to reason effectively about obfuscated patterns. To overcome these limitations, we introduce an LLM-based multi-agent system equipped with two key mechanisms: (1) an Orchestrator-Workers workflow that maintains explicit shared contexts while delegating specialized multimodal reasoning tasks, and (2) an iterative Evaluation-Feedback Loop designed to progressively counter complex obfuscation techniques. Using a dataset of 768 gambling-related websites, we benchmarked our multi-agent system against a single-agent baseline based on prompt chaining. Our system consistently outperformed the baseline across classification metrics, including precision, recall, and F1-score, demonstrating improved robustness against obfuscation. These results highlight the effectiveness of distributing multimodal reasoning across coordinated agents and offer practical guidelines for building automated, large-scale illegal content classification systems.
