In order to counteract the spread of aggressive polycode texts in the Internet environment, a legal linguistic approach is required: the legal regulation of counteracting “speech” offenses should be based on a comprehensive study using special knowledge from the field of judicial speech, integrating the provisions of linguistics, social psychology, psycholinguistics, cognitive science and other sciences speech cycle. The authors examine (from the point of view of substantive law and judicial speech) the main speech actions that constitute a threat to the worldview security of communication in a digital environment and are implemented through the generation of polycode texts. The paper proves that the concept of a “multimodal text” is not equivalent to the concept of a “multicode (creolized) text”, because the selection of data from linguistic entities is based on different criteria: sensory modality and communication channel. The classification of communication channels proposed by the authors, the types of relations between the verbal and iconic components of multicode texts, and other abstracts of the paper are the starting points for further legal and linguistic research of criminogenic Internet communication that threatens information (worldview) security in the aspect of judicial linguistic examination.
