Media text, emerging in the network discourse, attracts the attention of many Russian and foreign researchers, primarily because of the regressive changes dictated by this new field of communication. The greatest interest at the moment is the problem of identifying and studying such phenomenon as speech aggression, as it entails systematic violations of principles based on respect for human dignity, allows discrimination on various grounds, which leads to the formation of negative attitudes towards certain social groups, increases the growth of social conflicts and subsequently leads to violations of the legislation of the Russian Federation. In the work an interdisciplinary approach to speech aggression from the position of medialinguistics is realized. This approach makes it possible to qualify speech aggression as a multidimensional behavior of users of modern Russian messengers and allows us to identify universal features of speech aggression in network discourse.
