Online platforms have become fertile grounds for hate speech, often spreading through bursts of coordinated user activity. Detecting such patterns requires more than analyzing individual posts, as it calls for understanding the collective rhythm of online interactions. In the present study, we present SIACO (Social Synchrony Identification using Ant Colony Optimization), a nature-inspired framework that detects hate-speech events by tracing synchrony in user behaviour. SIACO models how hateful expressions emerge and fade collectively, using Ant Colony Optimization to refine linguistic features and improve classification accuracy. Upon evaluation on a Twitter dataset, the framework consistently outperforms both traditional machine learning models and transformer-based baselines, achieving up to a 10% improvement across major evaluation metrics. The framework also offers interpretable insights into the linguistic and temporal cues driving coordinated hate. The performance scores obtained highlight the value of looking at hate speech not just as text, but as a social phenomenon unfolding in synchrony.
