This paper aims to establishes a wider landscape about the way Brazilian Black Bloc uses Facebook tools to act politically. To reach this goal, we discuss aspects on the networks of the three majors Black Bloc Facebook pages and also identify post patterns related to categories previously established. In the literature review, we address the emergency of new dynamics of activism that uses digital networks to set up new ways of political action and also reinforce pre existing ones. Thus, we discuss the way global movements acts in terms of network articulation in local context, besides issues on decentralized and citizen driven collective action. Finally, we argue that the black bloc political action in Brazil is concerned to identity reinforcement, presents a dynamics that shows an engagement of one timer users, informs citizens about local acts and propagates values about group formation in international bordless basis.
