Modern realities show that there is a need to establish responsibility for the involvement of underage children in the activities of destructive groups that do not have a terrorist or extremist orientation, but pose a real danger to the physical and mental health of underage children, their moral and spiritual development. At the same time, the question arises in the use of legislative structures in consolidating such responsibility. Namely, what the concept of involvement covers and whether it will be enough to prescribe responsibility for the fact of involvement in the law. In addition, the question of the concept and signs of a “destructive group” is debatable. The article concludes that the most dangerous are antisocial and antisocial groups, whose activities are aimed at the desocialization, development and consolidation of deviant behavior of children. Many of these destructive movements base their activities on the dissemination and promotion of destructive ideology, including by posting malicious information on the Internet. However, encroachment on the information security of children by producing destructive propaganda content does not always fall under the scope of criminal law, which indicates the need to amend the current legislation.
