Social media platforms are known to shape and polarize user opinions and, increasingly, facilitate pathways toward ideological extremism. Among these trends, online misogynistic communities associ- ated with the incel (involuntary celibate) ideology have received growing scholarly attention. Previous work has primarily focused on ideological narratives and linguistic content within incel communities them- selves. However, much less is known about how user behaviors evolve over time, particularly before and after their engagement with incel spaces, and whether early signals can anticipate such transitions. In this study, we conduct a longitudinal analysis of Reddit users who participated in the r/incels community on Reddit. Our results show that engagement with the incel community is associated with a substantial in- crease in toxicity in both posts and comments, while hate increases particularly in posts after engagement. These changes extend beyond explicitly ideological communities: users who engage with the r/incels sub- reddit display elevated toxicity and hate speech even in subreddits related to leisure, entertainment, and everyday interests. In parallel, user activity shifts away from recreational and support-oriented communi- ties toward subreddits focused on social issues, indicating a broader reorientation of online participation. Finally, we show that future incel users can be identified with high accuracy prior to engagement using supervised machine learning models trained on linguistic, contextual, and interaction-based features. These findings suggest that online misogynistic radicalization follows detectable behavioral trajectories and diffuses across the broader social media ecosystem.
