One of the consequences of the emergence and development of the information society has been the increased capacity to exert negative informational and psychological influence on the individual psyche and public consciousness of Internet users. In circumstances where information intermediaries fail to comply with the requirements of Russian legislation restricting access to unlawful content, administrative-law restrictions in the communications sector — specifically, the «modification of telecommunications message routing» — have been imposed upon them. The purpose of this article is to determine the legal grounds, procedure, and appropriateness of applying this type of restriction. The principal finding is that communications-sector restrictions applied to information intermediaries result in limiting users’ access not only to destructive informational resources but also to beneficial information, thereby affecting the extent to which the right to freely seek, receive, and access information, the dissemination of which is not prohibited by law, is realized.
