We focus on weakening a dangerous community. The paper investigates a problem of an external and soft control of a community. At first, we checked an assumption about the connection between the features of the vertices and the presence of an edge between the vertices was checked. Then, two models were proposed to model a dynamics - a modification of Barabaci-Albert model and a new reconnection model based on the general classical ideas, as in the Watts-Strogatz model. Within the framework of such models, the control problem was naturally reduced to the separation problem. Furthermore, we proposed greedy and stochasti algorithms to solve it. The algorithms were applied to real and synthetic data and we shown their strengths and weaknesses.
